Here's a more in depth review of Fluoro:
Power: Fluoro has a moderate amount of power for a luxilon poly. More than BBO and 4G for sure, less than Ace and Element. On slow swings, I believe, due to the relative increase in softness Fluoro has more power than standard ALU. However, at faster swing speeds, ALU hits a bigger ball in terms of both power and spin.
Spin: Speaking of which, Fluoro seemingly fits somewhere in the middle of Luxilon strings. I've played strings with significantly less spin, but ALU/Rough certainly grab the ball much better. Luxilon Ace, for example, feels--even while fresh--like a stringbed of regular ALU that has been played to the point where it's worn thin. As a result, it's still going to grab at the ball, but doesn't bite like fresh ALU does. Fluoro has a similar feeling. does it bite better than most poly strings? Yeah, I'd say so, but not as well as most lux polys, other than maybe Savage, M2, or 4G.
Feel: It was a bit softer than regular ALU so there was a slightly more pleasant feel, especially on off-center shots, but I wouldn't recommend this to a person looking for a feel poly.
Groundstrokes: When I supplied plenty of swing speed this produced a heavy ball off the ground. Certainly comparable to Hyper G (I get more spin from Tour Bite than Hyper G). I don't think this string but feel too great for someone used to playing with a newer, shaped spin monster poly, but I don't think that's really the target demographic for this string.
Serves: Again, I felt like this string only accentuated what I was already good at. My serve wasn't magically better, but it did play like a similar, but slightly softer version of regular ALU.
Volleys: Point and shoot. If I were a full time doubles player who enjoyed ALU I'd probably switch to a full bed of Fluoro because of the marginally better feel and consistent response from the stringbed. This won't magically make you a better volleyer, but I do enjoy the way this performed up at net. Maybe an ALU/Fluoro hybrid would create a really nice stringbed for me, but I think that's doing too much, honestly.
Overall: Fluoro is to ALU what Schopenhauer was to Hegel. A great string, and one worth playing with, because it has something different and unique to offer. But let's be honest, we all want the good stuff.
