After giving up on finding the right truck and setup for sometime I think just knowing these 2 preferences will help you get out of the loop,
-find the tightness you like your trucks, like the REAL tightness where you are confident in doing tricks and ollieing over stuff knowing your board won't rocket or leave your feet. I discovered I like my trucks tightish and everything got so easy, getting my nose manual and nollie heels more consistent
-find the right height, it might not be as critical but for me I prefer my trucks like a mid or between mid and low cause you get a faster tail hitting the ground feel, some people want to feel levitated and that's all you. But if your trucks are the right tightness and height I guarantee it'll just get you back to pure skating and no thoughts about your setup
Everyone's probably gonna say the right bushings and all that but really I think depending on how truly truly tight you like your trucks then you can consider bushings cause I feel you can skate stock bushings on any trucks with any tightness it's just aftermarkets are more suited for your preference is all(I like tighter trucks so harder duro is gonna work better than having a medium and cranking it just to be able to turn a little more but lose some board control), I like the stock thunders but the after market harder ones just work better cause I don't have to expose as many threads tightening and the bushings don't wear and break as fast( the stock Softs kept getting soft again from the wear in only a few session and the tops were cracking)
