Hey guys. So I currently have a 2015 Pro rmk 163 with the stock 2.4 track. And I will be upgrading to a axys this year. But I can not decide if I should go with the 163 or 155. I find my current 163 to climb well but it is a work out to get it to wheelie or play around with it all. My last 155 was a wheelie machine but liked to trench out. So I am wondering if the new 163 with the 3 inch is more playful? Or is the 2.6 any good ? I rode a axys 155 3 inch last year for a bit and it was a awesome sled to ride. So I'm debating which length. Anybody have opinions?
