Been a while since I posted, but it has been summer and the backcountry riding is a little rough. I have received my ProClimb M 800's. All 153's. My plan is to disect the sleds and determine piece by piece which parts can stand to lose some weight. I'll be looking at chassis parts, suspension parts, shafts, plastic pieces and feul tank and seat. Hopefully I can find time to update every day or two.
