using quark 125 monstor, which motor?

i think i'll get one of each
neu 1515 1y
8xl (is the feigao/wanderer/nemisis good or get purple feigao/)
any ideas of exactly which of each i should get
this will be in a g2r not sure which pinion yet.
this track is a pro truggy style track, big jumps , not many long straights

oh yeah THANKS for responses i'm still learning and very appreciative of all you knowledge sharers.






i would just love to spank those nitro guys or at least have a drivers chance.
