Delete is just compensation for wide boards.
If you narrow and raise the chassis the t motion works better than a locked skid.
Locking the skid is basically like adding board height.
When the t motion skid flexes upward it allows the boards to make contact to the snow, as soon as there is any contact it lift weight of the track and causes a wash out.
Just like if you where on a motorcycle and landed hard enough to drag your pipe it will slide the azz end around.
I proved it with an xm years ago.
I raised the boards 2" and narrowed them 3".
With t motion intact I slaughtered axys s on sidehills, the only comparable was my modified cat that did better because of suspension and track.
But, it's the board width and height that is killing it, not the t motion.
