Dude... I started as a snowboarder, and I thought yeah I'll be the man with my short skis, so I bought 141 tms, and I was like 5'3 then... like 2 months later I got some 168 scratches and they make a maaaassive difference. You can stop way more for stability. You might be able to learn sketchy 3s on small skis but trust me, after a week you will want something around the same height as you, not below your neck
