Ski-Doo Summit X vs Polaris PRO-RMK for sled skiing? I need a sled for accessing backcountry ski lines in Tahoe. We'll be tandem-ing up to access the lines.

Am I right in thinking the best sled I can get for this purpose is either the Summit X or PRO-RMK?

I'm very light - I weight 130 lbs. The people I'll be riding with are typically around ~170lb.
