Replying to Quick question of bindings ive got surface nine lives

I had them center mounted and there a 172 90mid 106 tail but I'm finding that my skis are feeling a little out of control.or light almost floaty the back and tend to catch an edge when turning I used to have a set of 154 wrapped edge with stringers heads and I was mounted like three inches back further a few years ago then had them centered as well to make spins and grinds easier, I'm a filmer of free skiing that's all I want to do any more so I switched it up to begin more free skiing but that floaty feeling is sketching me out a bit should I move it back a few CM's or
