i second you on the don't mount them center. they're going to ski so much better if you mount them a little bit back. and with a ski that soft they're definitely going to snap if you move the bindings back and have holes in front of the toepiece.
they really do rip, you're going to have a fucking blast on them. i couldn't believe how well they skied on groomers. by no means are they great, but they are manageable, far better than i had expected.
