Well first trip with the new Pro-Motion installed. Before I go anyt further, here's my setup, 163" with an X3, Raptors all around, Alternative Impact 36" front end and SLP Powder Pro Skis. I'm 6 foot and weigh about 230, for comparison.
First day out I had the front end set to the narrowest setting and for "my" liking it was to tippy. I found for me and my riding style it just seemed to tippy, epsecially on climbs that were rough or the snow was set up. I know alot of this had to do with the front end but I know the Pro-Motion had some input with this as well. In the powder it was extremely easy to lay over and maneuver.
Half way through the first day, I set the skis to the widest (still narrower then stock) and a way a I went. I also played with the rear track shock spring and once that was set, I moved to ajusting the front track to get the right balance.
Okay, once I got the suspension and front end set to my liking, then it was time to start evaluating.
Now with the above combination, I did notice a difference with the addition of the Pro-Motion. While this is not the missing link and makes the Pro majical, it does change the handling.
What I noticed was I could feel the sled begin laying over with the lean easier then stock. Where I had times before, I would jump over to one side, I found myself staying in a neutral riding position more then normal. While it doesn't completely take away wrong foot forward, I did seem like I was going into this positon less. When I would go into wrong foot forward, you could really lay the sled onto its side and rip it around. Hopefully that makes sense?
As far as sidehilling, for me it again seemed like I was going into wrong foot forward less then before. Again, not a bunch but it was different then stock.
It seemed like I could sidehill more hills with staying in a neutral positon.
Overall, with the combination I have and the additon of the the Pro-Motion, it made the sled a tick better for powder riding. I still have some very fine tuning on suspension but all in all, I'm happy.
