Depends, a EDGE chassis can be a RMK or SKS which got longer then 136"
My XCSP edge is a 121" at the moment and plan to convert to 136" EVEN then I wouldn't call it "great in deep pow" !?!? 144" & 155"+ are what you want for deep pow mountain riding. Where in NE you at??? Round here I'd be content w/ 136" Most I know who ride here all have 121"
