I think the only real drawbacks to these trucks are the sloppy shifter linkage (the guy who engineered that was a genius) when they wear out and the 10.00x20 tires that are hard to find that go on the "Chicago Wobbler" tube-style Dayton wheels that suck really bad.
There are three of those things at work (although they're tubeless 9.75 and 8.25x22.5s) and two at home that are the 20's.
I know shipping would kill you but do you want front disc brakes for that? I have an axle that'll go right in.
