I have a savage x and I put it 2 wheel drive some time and I had a lot of fun but it's hard on the drive train

so I'm looking to buy a stadium truck the MT2 G3.0 or the Firestorm and my question is if I like the 4wd and the 2wd should I buy the MT2 G3.0 and use it on 4 wd and some time on 2wd ???

and if some body tried the MT2 on 2wd is it as fun as the fierstorm and as fast or the extra height make a big difference ???

and a ohter question wath is the difference between the T3.0 and the G3.0 ???

thank
