right now i’m on 6.1s, and an 8.38. it’s super fun, but i can’t speak to it as a forever setup.
i don’t skate transition much, so im not really helpful. my experience with 8.75 trucks is usually street stuff, and i do like wider trucks for a few reasons, but mainly stability and less turn. indy 159s, venture 6.1s, ace classic 55s, thunder 151s, i’ve enjoyed them all. a lot. more than most 8.5 trucks actually (which doesn’t make sense to me). this makes me feel like some of these truck geometries are scaled to fit 8.75 ideally. i enjoy the ollie on the wider trucks, and hills. i also feel ok on some of my very limited stalls on coping.
wider trucks turn slower. some of the og pool gods use 149s or 139s, for quicker turning. it is noticeable when you try it.
for me, i’ve not seen advantage in 169s etc. they just felt heavy as shit, but i’m a weakling.
i also routinely extol the virtues of venture 5.0 lo’s so don’t listen to anything i say.
