Agree, I have toe drag way more often than heel drag. Gas pedals are a must. Most bindings have them built in now so unless you're rocking size 11+ at 0, 0 on a ski, you should be 'okay.'
I ride +/- 15 and have both my bindings set back toward the heel edge a bit more to minimize toe drag. I like to bolt the bindings up loosely with boots strapped in and mess around with toe/heel edge stance a bit to find a happy balance.
