For reference, I weigh 135 and I used the wheels session skating on a wood floor. I'm so grateful that I've had the opportunity to try these wheels! I was really curious to compare them to my 92a turbos.
I really liked these wheels (nicknamed "the foxes" because FXX is hard to say). They had a lot of grip at my rink right out of the package, which I appreciate because I don't enjoy breaking in wheels. In that respect, they were similar to my rollerbones 92a turbos. However, I did feel a little slip on the wheel when I was at a fast full stride...only at the end of my stride, and the wheel was no longer in full contact with the floor at that point. I think this would probably resolve with more use.
I raced in them (and won
), and I plow stopped without difficulty. I had enough slide to not feel "glued" to floor...a controllable slip; I never felt like they might just go right out from under me. There was only that one point in a hard push with my leg fully extended when they let go a little.
The wheels are very light, and the 187 mini bearings (nicknamed "the kittens" because they are so darn teeny and cute) make them even lighter. But when skating, I really didn't notice that my skate felt lighter than normal. It might make a world of difference for someone that's in a heavier skate, but my skates are pretty light to begin with.
I did notice that I tired a little more quickly than usual. The roll wasn't quite what I'm used to, but I am inclined to blame the bearings. I would have to try the "kittens" in another wheel to know for sure, and I don't have the spacers required to do so.
Although I do really like the grip of the wheel, there is an X factor that holds me back from getting too excited about it. I just don't know exactly what the issue is because there are so many variables, but I have pretty decent endurance and I was noticeably more winded and had tired legs, which would negate any advantage of having a lighter wheel.
I would say that the 92a turbos are a comparable (probably superior) wheel for my purposes, although not quite as light, and they have do the advantage of cost and more flexibility with bearings options.
Oh! I also found that my zero nuts rubbed the hubs a bit so I had to use regular axle nuts.
It's not a big deal to me, but I thought it might be noteworthy for someone that wants the lightest possible skate and loves their zero nuts.
