i have had problems with both of savage and terra crusher i dont have knowledge about xtm..but i recomend savage because of speed and good for jumping..xtm looks weak to me..ask bonefrost he got a xtm few weeks ago if i am not mistaken..savage although sometimes it makes me pull for minutes before it starts i still love it..any mt u pick you would experience different problems..try comparing them at the lhs see which one would catch your attention first and the one that you cant let go..then most likely youll buy the one that you cant let go
