Just skated my sample 93a 56mm radials. They're nice I like em. Functionally they're very similar to dragons but feel a lil more like the f4 spitfire kinda formula which is nice. Still bouncy like a softer wheel though.
Maybe a tad harder than dragons too, not sure didn't do a side by side. Pretty certain they grip/drag on rails and ledges a lil less than dragons too which is great. But definitely still noticeably more than a 99a f4. Probably a tad more than a 97a f4 I think.
Skated rough ground and they felt really fast and held speed great. Not sure if they will feel gummy or slow on smooth ish ground, can report back, but my instincts say they will feel fine.
So great wheel, powerslides great, feels great. But unsurprisingly not a replacement for 99a f4 if you need certain hard wheel characteristics
