I can't comment on the ez-ryde but I have a kmod gen 2 on my apex. I love the kmod, would not hesitate to put it on my next sled. It keeps the skis down when you want and can pull the skis up if you pull back and that is on the smallest setting on the coupler blocks. The ride is amazing. I cam off a REV before and stock suspension on the apex for a season and the kmod rides 10x better. Feels like it has more travel, soaks up the bumps and "floats" across stuff in my opinion. Also seems when you hit cross ruts while climbing it doesnt want to stand on end, it will push through them and keep the skid on the snow.
