realistically, you're probably fine on the squires. as long as your DIN isnt pushing 10 or 11, you're safe. yeah, the griffin is a little bit burlier of a binding, construction-wise, but like i said, the biggest difference i noticed was on wider skis that traditionally put a lot of torque on the binding when tipping them up on edge. the jester (same footprint as the griffon) on a wider ski felt much more responsive than the same ski with a PX12 or STH12 on it.
