Wide trucks aren't difficult to get used to, I have ACS 651's (6.5 inch wide) on my skates (see avatar pic), use them for all kinds of skating too
I would advise anyone reading this to look for NOS 651's if you're considering them though as the remakes are garbage - I snapped one at the pivot pin just session skating a few months ago.
It's also worth using narrower wheels with the wider track trucks too as wider wheels can increase the likelyhood of tangling them together.
