my last set of wheels were the v cut 53mm grocery bags and currently im on "og wide" 54mms (both AG formula)
definitely prefer the og wides because the v cuts have a much larger riding surface. The og wides are a lot like classics and honestly slide about the same when new (just cant hold slide for as long due to the urethane - good quality, doesnt chip or flat spot easily and works amazing for feeling smooth on rough ground but cuz of that slides worse than an F4 or STF)
overall id say its a good choice. the 99a is a bit softer than traditional spitfire 99a which is a given because f4 is top tier shit. wheel shape definitely matters though. I bought these instead of spitfires cuz sml arent slow unlike other wheels and the og wide shape is skinny and proportional-feeling enough for me to skate basically everything (including rough ground which I find hard to skate even on 101a spits), and in Canada spitfires are a good 15$ more expensive and I could use that to buy a cart from the Kush dispo.
all this being said, im currently on a bit of a wheel thing where I try all kinds of wheels before I try spit f4s again for the first time in years. Last wheels were some OJ mini combo 101a that slid well and felt good but just didnt keep speed as good (might've been cuz of coning or obscenely wide riding surface)
