skated some Wayward Puig 52mm wheels this weekend.
similar shape to the F4 classic shape. felt a little harder/slicker than the 99a, but not as slippery as the 100a. I kept expecting them to flatspot or in some other way disappoint, but they skated great. we'll see how they last...but initial reaction is they are great wheels.
next to used 52mm F4 classic
