Replying to Hitting a summer setup

So I'm fairly new to skiing, but I've had a summer setup for snowboarding for a while. Recently I've realized it's been hard for me to get the complete rail on skis, and I'm not totally sure why. I might just suck at skiing, but also I've thought that it could partially be all about the drop in when I go to hit a rail. It's super hard to adjust your take off when hitting a summer setup due to loss of edge control and limited turn ability. So NS do I suck at skiing that bad, or is it just hard to dial in how to drop in on a summer setup?
