I found this on one of my (rare) visits to the US forum today, dated 10th June 2009.

"I bought my first Fleshlight near the end of last year and, in the time between, collected every texture that ILF offers. (I know, I am an addict!) Anyway, I have never posted on this forum, but I have been lurking for some time. So, I am always seeing people asking about different inserts and that made me decide to whip up a review about them all. Hopefully, this will be useful to somebody since I am taking the one variable from the equation, the different users. While I know my experience will not be the same as everyone, you can at least see how each insert or inserts will compare to what you currently have. Here it is:
Stamina Training Unit
ILF claims this is one of their most intense sensations ever, I am not going to argue. The insert, at its widest point, is the same diameter of the Super-Tight (1/2”) insert but unlike the ST it contains hundreds of bumps lining the inside. Now, that doesn’t sound particularly interesting but my yank begs to differ. It feels so good from the first time you slide in there and just keeps getting more intense the closer you get to orgasm. When you do decide to unload, or when you can’t stop yourself, it becomes even more intense as those bumps caress the tip of your member.
Butt / Super-Ribbed
First of all I must say that anal sex in real life doesn’t appeal all that much to me for the obvious reasons. However, the Fleshlight removes these problems leaving me wishing the real thing were as wonderful. The Butt orifice is distinct in its appearance, but also in the fact that the distance to the insert texture is shortened compared to the Lady entrance. The Super-Ribbed insert is usually referred to as the Super-Tight Super-Ribbed insert by most people because it also shares the same ½” diameter of the smooth Super-Tight insert. However, as the name implies it is ribbed; there are tons of little valleys spaced extremely close together in there and it is a really awesome feeling. If I had to rate this one myself based on its intensity I would probably place it above the STU. Those ridges play hell on the tip of your penis, in an extremely pleasing way. I definitely find that I can reach orgasm much faster with this texture than the STU and once the orgasm starts I HAVE to stop moving in and out because my head is so sensitive by this point.
Raven Riley / Lotus
ILF’s newest insert is supposed to simulate vaginal sex perfectly. Now, when I first got this one and tried it out I was completely disappointed with it, but after having it for some time now and getting a chance to use it more I have really come to love it. The vaginal lips and clitoris are so much better to look at, since they are molded after Raven Riley, than the standard Lady orifice. Another thing I noticed about this sleeve is that the material it is made out of is noticeably softer than any of my other inserts. Anyway, as you first start into the Lotus and pass the tight entrance you find yourself in a wide opening that ends in what ILF calls an inverted node followed by some more chambers like what you find in the Wonder Wave. I will be the first to say that this insert is not anywhere near as intense as most of my other ones, but if that is all I said to describe it, I would be doing it a severe injustice. I can only explain it by saying that it is extremely pleasing to use; the soft insert feels so good and then you reach that inverted node, which curls backwards when you pull out past it. All of that together makes for an amazing FLight with an unexpectedly strong orgasm at the end.
Lady / Vortex
The Vortex is difficult to explain in words because the interior is quite complex. I suppose I should start by mentioning that there are multiple seams or ridges that spiral around the interior as they run the length of the insert. Now, that alone would be intense, but there are also multiple chambers of varying diameter. At its tightest point it has the same ¼” diameter of the Ultra-Tight insert but the variation in diameter plus the spiraling ridges are impossible to explain in words. All I can say is that it is one of the most interesting sensations of all of my inserts. If there was any insert that you should get in the Ice color, it is this one. It is so awesome to be able to see your shaft running through those sensational chambers!
Butt / Speed Bump
Supposedly the most intense sensation you can get with a Fleshlight is the Speed Bump and I agree. Now, if you were to compare this insert with the STU you would see that they are basically the same setup, but how they are executed makes all of the difference in the world. The Speed Bump is yet another ½” diameter sleeve with the well-known Super-Tight Super-Ribbed moniker. The STU and SB share the same staggered bump pattern, but while the STU has large, closely spaced bumps the SB has smaller bumps that are spaced considerably further apart and the sensation is totally different. It feels like 50 little fingers rubbing your head and shaft as your plunge in and out of this insert. Lasting takes serious practice in this insert, you just have to completely stop moving your penis when you get close to orgasm, but let me tell you when you do decide to let go it will drain you like crazy. It is definitely a knee-trembler.
Lady / Wonder Wave
If memory serves me correctly this was the first textured insert available in the Fleshlight and it still is a very good one. As the name implies, there are many sequential waves lining the insert. I was a little skeptical of this insert since the FL community hailed it as one of the all-time favorites and that sets the grounds for a big possible let down. Yet again my worries were thwarted after using this one a couple of times. Those continuous waves just caress the tip of your penis and are just as pleasing as you rub back past them as when you push through them. Even with the release of the Lotus most people swear this is the more realistic insert.
Stealth / Original
I was not expecting much from this insert since it is looser than any other insert I have, but after about the second session of using it, I REALLY like it! It is exactly the same as my Ultra-Tight, but 4 times wider on the inside, now that might make it sound to wide, but trust me it isn’t. I suppose I should have just said that is like the UT because it is totally smooth. Anyway, if you want a slow, relaxing session that still ends with an amazing orgasm, then grab this one. It should be mentioned that I used this insert after trying every other textured insert available and I still like it. Now, I decided to get the Stealth entrance since I didn’t have it, and I am glad I did! It is shaped like a coin slot and it WRAPS your dick in a way that resembles the Butt orifice but I find it more pleasing.
Tera Patrick / Twista
INTENSE! Absolutely no other word for this insert! It will have to squirming around as you stroke your yank! I rate this insert as a tie with the Speed Bump on the subject of intensity. The interior has a spiraling ridge that runs the whole length and on top of that the canal gets tighter from beginning to end! In the end, as much as I like the Lotus, this one wins when it comes to the best orgasm.
Ok, as I mentioned before, everyone will have a slightly different experience so don't hang me from the yard-arm if you disagree with any of my reviews above. Also, I know that penis size affects the feeling so, for reference, I am an average 7 inches long with average girth. Now with that out of the way, if anybody wants more elaboration on a certain orifice or texture, just let me know and I will be happy to do so."
Whew!
I agree about the Lotus and the Twista, of course; the WW too.
