I finally got around t skate some formula 4s (99a 54mm classics) definitely the best wheel out, slide super well and have such a controlled slide but also grip really good and dont make me slip on parks.
Also, the best cruise/filmer wheels by far are the OJ keyframes, those wheels are light years ahead of other cruiser wheels
I know I've said this before but if you like F4 Classics then maybe try Wayward slim cuts. I know it's a new brand and Spits are well known/good but these are good wheels. Made in the states and they feel very similar to formula 4s in both the slideability and the grip which is rare, at least to me. In my experience, wheels either feel a little more slippery than I'd like such as Bones STfs or too sticky like Rita NRGs (Please don't stone me Xen and/or Steve! Waywards and Formula 4s are the only wheels I've skated in recent memory that had a perfect balance. I just like way Waywards slide just a hair more.
The only real differences I can tell is that my Waywards seem easier to make slide at slower speeds but at higher speeds they seem to grip just as well formula 4s and these Waywards have a slightly crisper slide where as the F4s are barkier.
So far the only thing I can see that would make these Waywards not perfect, other than a premature flatspot, is if the wheels turn to that nasty ass yellow color but if they continue to skate this good, then I couldn't give a shit!
