from what ive seen the sv2 has less steering than the sv and appears to less predictable, all we run at our club is cougar sv's (and sv 2) and durango dex 210, i drive an sv with 8 mm longer chassis and my son drives a normal sv neither of us likes driving the others car, so its down to personal preferences, ask at your local club, we have just had a team c mid motored buggy turn up who used to drive an sv2 and he says its so much easier to drive faster indoors
