i have had my xt2 for over 1 and a half years now and want to step it up into something more experienced. can you guys tell me what each of the following buggies are good at (pros and cons) i have no price range and have many freinds that are very experienced builders. mbx-6, mp9, xb808, Jammin X2 Pro, 8IGHT 2.0. these are the main ones i was thinking of. thank you
