Replying to FKS XXLs on 86 mm skis?

Hello fellow NSers, i have a couple of questions.

I just ordered a pair of atomic infamouses (86mm center) and I need bindings. I could get the Rossignol FKS 180 XXLs (117mm brake) for pretty good price, but the brake would be a lot wider than the ski. Would the difference be too big? Could they be bent in? If I mount them, will the brake drag while carving?

And would the 180 be way too sturdy for me? I'm 175cm/5"9' and about 60kg/130 lbs, advanced & aggressive skier. I ride mostly park and streets, but also powder every now and then.

Cheers!
