My son, who is 10 now, learned to slalom on the TRA, great ski, very stable and forgiving. I think this ski has a lot to do with the progress he has made in the last 2 years. It instills confidence because it never surprises them but will perform when pushed unlike a slalom out of a combo set. Last year he was getting through 26 mph and especially at higher speeds it looked as though he was having to force the turn to gain angle, I felt the ski was starting to hold him back a bit so we upgraded to a Vapor this year. The TRA is a great, affordable starter ski. Your son will love it.
