Mounting 188cm nordica 12tt's

I owned a pair of 177cm nordica 12tt's that I ended up drilling twice. The second mount was about 3cm back and they skied really well at it. But they would still be overpowered at fast deep turns. When those died, I picked up a 188cm pair and am thinking of mounting them about 3.5cm back with dynafits and beefed up scarpa lasers as with the last pair. Too much beef for little boots?

On the positive note my dynafits have enough days on them where they won't release for anything. I cartwheeled down a nasty pitch and tacoed the last pair and the little guys never came off.

If you're overpowering them in turns mount them more forward, not more backward. The further back you mount, the easier they release from turns. More tail = more power.
