Like was said, no swaybar with stock shocks is going to be bad, it will bottom hard on sidehills, regardless of rider weight for the most part. (Unless you are very light.) The XM sleds are so easy to tip up, no reason to pull the bar.
I did the quick disconnect on my Freeride last year, in hard spring snow, and it was easier to tip around, but it got scary, I didn't like it. The shock would compress enough that when it punched through the snow, the ski would come back up at me and almost throw me over the bars. With the bar hooked up, it didn't do that at all.
