what track is the 1.75? challenger? ripsaw? other?
in most cases I say bigger is better but some tracks are trenchers no matter how tall the lug like poo competition track assault track for example the worst trencher built for pow but great on everything else.
at this point no matter what u put on u would be fine nothing but hero snow everyplace and the popular spots are like a hard pack trail till u get way way off and up over the pounded.
what is your intended ridding if just planning on playing in the bowls and what not your stocker will prob do .
if the place u intend to go gets 5 ft of fresh the day u get there they will both be worthless
