K9FCAT This is some info I got off the net when I had one of those sleds. I never ran it so can't vouge for its performance.
Polaris 10M5 weights(49.5 Grams)
HPE Black Blue Primary
HPE Red Secondary
D&D 60/40 helix
If I remember that sled had no low end upshift with the stock setup. The 60/40 helix makes sense in that regard. This setup might work pretty good if you aren't runing in deep off trail snow. Peace, beeler.
