I have just turned 180 miles on a set of Powder Pros - they work great on hard packed trails - not pushing and very responsive no matter what speed. The placement of the carbide seems to be farther back than the AC skis. I beleive this contributes to the bite as well as changes the effective chamber to lower steering effort. I am very confident approaching turns and getting on the throttle leaving the apex after bolting on the Powder Pros. I am running 6 1/4" X 60 carbides - ice is not an issue.
I have not experienced any darting yet. I am running 3/8" tow out & limiter strap on the middle hole with SP suspension. This weekend I will take the tow out - out and see what happens. Yes, the steering effort is significantly reduced. Mine was really easy to turn with stock tune but pushed like crazy especially while exiting a sharp turn under hard acceleration. I sucked the strap up and the effort was considerably more than stock tune.
