i'm trying to decide between surly, formula, or IRO (made by formula) track hubs.
this is for road (city) not track. they'll be laced to velocity deep-v's.
i want flip-flop 36h preferably black.

which of these 3 would you recommend?
do the iro/formulas even come in 36h? and is 36h vs 32h even that important for strength?
