Based on how much I liked the QST 99, I would get the QST 106 in a heartbeat. Unless it's clear that the 99 and 106 are radically different animals. I found the 99 very compliant, light-feeling swing weight and responsive, yet damp enough to be great in crud and chop as well as moguls. Lots of fun and confidence inspiring, for me one of the better 98-100's. FWIW, I'm 5'-10" and 145lbs, so a heavier skier may have a different response.
