I have both. A 2014 Proclimb, and a 2013 Pro. 163" and 162". Both work really well. Amazing what the new sleds will do. I have had 4 Pros and a 2012 Proclimb. The Pros were 2011 & 2012. Still have the 2012 Pro. The 2014 Proclimb is so much better than the 2012 Proclimb its crazy. Even though they didn't do a ton of stuff, the upgrades they did was substantial. The 2013 Pro is better than the 2012 Pro. I can't comment on the 2014 Pro, as I haven't ridden one. Some say they are better. My 2011 Pro had a turbo. I have had a fairly long list of turbos in my stable in the past.
With that said, I have a quite a bit of experience on both. Our riding style is mostly tree bashing, some climbing and mostly backcountry riding. First off, I am NO Chris Burandt or Matt Entz. I am fairly proficient at boondocking but make no claims to be a star.
My opinion. The Pro has set the bar regarding backcountry riding, no doubt. The 2014 Proclimb is as good or better in everything other than a VERY VERY technical sidehill. One that is probably only ridden .5% of the time. The Proclimb is easier to ride and sidehill. I will get flamed for this statement, but it is my opinion. Very little rider input is needed. Am I saying the Pro is hard to ride. Not at all. Its a great sled. We did quite a few comparisons this winter and the Pro is the King when it comes to sidehilling and getting on top of the snow, DEEP snow that is. The Proclimb was right there with the Pro in the very deep snow. Get in the snow that is what we ride 90% of the time and the Proclimb would perform better. The 2.6 track really works well. Another thing that is very obvious is the snow build up. Many scoff at it as a marketing ploy. HAHA. It is real. The Proclimb holds very little snow where the Pro seems to hold quite a bit. No, we haven't weighted them, but the difference is there, and real. Climbing in deep soft snow, the Pro is a lot closer to the Proclimb than we thought would be. The Pro climb will out mark the Pro, but not by much. In the heavier snow, the Proclimb is at definite advantage due to the track. At the end of the day the Pro tires me out more than the Proclimb.
Eric Woog\VOHK did a write up last year pertaining to the two sleds and I feel hew hit it right on. It would be interesting to see the same comparison to the 2014 Proclimb, as it is a better sled than the 2013 he wrote about at that time.
Again, my 02. Many will disagree. that's cool. we need debate to keep things lively.
Oh yea, the reliability?? I blew up the 2011 Pro due to fueling of the sled (turbo). My fault. The other 2 have been perfect.
Bottom line. Both are incredible sleds and will provide plenty of performance.
