Hi i bought a krooked Zip Zinger board about a year ago and was just using some venture trucks and crap wheels as a commuter but i started skating heaps more. So i went to extreme skates and the guy put me onto randal 150's with z-smooth 63mm/78a wheels. I've gotten a lot more competent since then and am wondering if there are any good modifications i cant make to it (i have messed around with how loose i make the trucks etc) like different bushings, 70+mm wheels, better bearings or anything.
I live in Brisbane, Australia which is an EXTREMELY hilly city so what i want to do is have more control at downhill speeds. This setup is very very carvy on the sidewalk but after a few turns down a hill i just have to bomb straight down because it just becomes to hard to carve at speed.
