for a 6 footer, your gonna want something TURNY. exskates, originals, something with a real severe kingpin angle. another one id look at are Uptrucks. they are a brazilian company, and the trucks are solid urathane, and flex to turn. they will really crank around. um, what else... Bakus, those would work too. nuclear pickles would be dope too. id say a torsion truck like the exskates, bakus, or pickles would be best.
for wheels, id say mid 80s durometer, sized about 76-80mm. think about some deep wheelwells or something so you dont have to bump it up any higher, possibly droppin the trucks throu the deck. thats where the design of the board comes in. how you plannin on building it btw
