As a parent of two racers, I know how to buy race skis.
But I went into the ski shop to get a pair of twin tips for my 14 yr old son who is about 5'6" and the staffer recommended a 155 length.
This seems to be rather short - his GS skis are 170.
My son wants a pair of twin tips as an all mountain ski. Any park time is spent doing jumps or in the half pipe. He is not big on riding the rails.
So my question is how do you size twip tip skis?
