honestly i dont know!
at the shop i went to, they guy there like told me everthing thats good...he went over my WHOLE truck and he was amazed that i ride with dogbones(he strongly suggested MIP CVD's). he also said that the newest chassis is the best you can get, 2nd best, believe it or not, is the tub!(but tub = more weight). I also saw some trucks like the Savage and Revo up close, along with the nitro evader. they even sold the very first bach of GT's!!!! [X(]
I got done my little shopping and all i need now is a new Radio and engine. I also saved like $25-$30 from getting my parts there then from tower! If that shop was near where i live, i would so go there all the time.
The shop was in southern PA, its called "Extreme RC Hobbies"
