This is a very touchy subject on some forums. Why I have no idea? Some people want to believe what they ride is the only thing worth riding and everything else is junk and you should be ashamed to ride anything but a Doo.
Anyhow, here is my thoughts, mine and mine only.
Having been on Doo for a number of years and watching people who I ride with excel as a rider on the RMK I was on the fence until this past fall when I sucked it up and picked up a Pro. I had previously had quite a bit of seat time on them and each time my confidence grew greater on the Pro for the type of riding we do.
The release of the T3 Summit was a big selling feature for some people but it didn't address the Summit's short comings that are the same on the XP and XM. The new Summits with the flex edge and t-motion, small changes to the geometry and such do turn okay riders into good ones. The ability to initiate a movement with less effort is nice, but I don't find that was the downside of the Summit.
The RMK holds a line better, be its suspension design, or the way its chassis design performs it works better for backcountry technical riding. The more aggressive you ride it, the more you get from it. It took me a little time to get used to the RMK steering, but not so much that it was foreign. I find on the RMK you don't always have to be as far forward, it is more forgiving where you stand but instantly responds to rider input in a predictable way.
Once of the things I continue to dislike about the Summit is the way it wants to dive. Typically the Summits are very soft where the Pro chassis is very rigid. Just look at a Summit climbing a sled deck ramp, the front suspension collapses where the Pro is very tippy. Small changes to the Pro suspension usually can be noticed right away, where with a Summit you can change a lot and it still rides the same. The Summit an its torsion springs are in need of an upgrade. They make a good mountain sled that works awesome on bumpy trails. I would rather have an awesome mountain sled that works like crap on the trails, basically the Pro because I don't ride the trails other than to access the back country.
If Doo could update their suspension, step back from being so far rider forward as I think they have continued to go forward to try and compensate for a bad design and fix the front end so it doesn't dive I would go back to one. I love the etec and the way it makes power, I don't like the crappy TRA and it having to be rebuilt often. I think Polaris has some great clutching even stock, and the Team products don't seem to have as many issues. I do like that the Pro is lighter, being a light guy I can feel the difference of the sled being lighter.
For me, the Pro RMK works better.
