pro's and con's

D60's have alot better steering vs. the rockwell
rockwell's have alot more strength vs. the D60
D60's are more expensive to set up vs. the rockwells
rockwells are alot heavier vs. the D60
D60's have alot of gear options vs. the rockwell has only ONE, the one that it comes with which is something close to a 6.17 (just guessing, someone please correct me if I'm wrong)
replacement parts are more expensive in the rockwell's vs. the D60
D60 parts are easier to get vs the rockwell's
rockwells use a pinion brake instead of brakes at the wheels. which if not set up right can be kinda scary for street driving. Hmmmm, what else did I miss?
