Does anyone have problems with the fitting heights for Shamir progressive lenses?

I like their products and I know they chose their fitting heights b/c that is what they feel gives the best possible vision.

The Shamir Genesis in Poly is a min. of 22 mm.!

It seems like most patients I fit have 17 or 18 - so I could use their short corridor (Shamir Piccolo) but...why use a short corridor when I can use a different prog. lens that fits and is not "short corridor."

I just want to know if I'm the only one that has issues with their fitting heights....b/c otherwise I really do like their products!!!
