I ended up sending back the Sarken's and ordering a pair of G14's which fit great.

I have a pair of Millet Summiter's that I picked up cheap at Sierra Trading Post. They are made of stretch Gore Tex XCR and work great. The only drawback is they don't have side zips.

I'm not excited about cutting the lugs on a pair of $440 boots...I'm still searching for crampons that fits before I resort to this option. I have the Sarken Sidelock and I'm curious if the Leverlock would work better with the Nuptse's. Has anyone tried the Leverlock which has a different heel mechanism?

I just purchased the Sarkens via mail order (I live in the Midwest and we don't have any shops in town that sell crampons). I ordered them with extender bars and they don't fit my size 47 Nuptse's. They are long enough (supposedly up to size 50's) but the heel bail doesn't fit the groove in the back of the boots. The company I purchased them from was going to call Petzl for advice. I'll post any replies if they have any information.
