Replying to Will I regret putting Pivot 18s on my pow skis?

Have a chance to grab some 2 year old new FKS 180s for absolute dirt cheap.

I'm looking for bindings to put on new 191 K2 Catamarans (120 waist). I'm 6'3, 200 lbs, pretty aggressive skier, but I'm not hucking 50 foot cliffs and I know I don't need an 18 din binding, but the price is almost too good to pass up.

I've read that Pivots aren't the best choice for wider skis because of a narrower mounting point. Also I'd rather not have a binding as heavy as this needed but I doubt I would even notice it.

Should I just look at a lower din Attack or Sth?
