Put a 2012 155 skid in my wifes 700 mid season last year. Been an awesome sled. Had a buddy borrow it yesterday, rode all day with snow over the hood.
I would almost say it trenches less then my PRO.... probably due to the slightly lower track speed.
It gets up on the snow almost as good as the pro, and soooooo much better then with the stock skid in it.
When I installed it I dropped the front mount hole about 1/2" down and back and left the rear in the stock hole.
No issues in over 400 miles
