Snowboard bindings placement?

Well in the end binding placement always comes down to what you like. There is no best placement just what feels right for you. Also I just wanted to inform you while you maybe right the whole thing about you riding "switch" since it was your first time lots of people have that happen. You feel like your good both ways but normally this is just a bad habit that you get from trying to control the board and you just make up for spinning by switching sides. Before you decide this is best for you, you should focus on riding in one fashion first. Also last thing on the binding setup. I would try a 15/-15 or "duck" stance it might feel better since if you rented the settings are normally 15/0.
