Thanks to Matt's PM'd suggestion, it's off - indeed, I WAS inadvertantly clamping the threads down trying to turn it off, so they were biting in more. In fact, once I tried turning it off holding at the open end, well, it came off like butter - no boa strap required! D'OH!!!!
I had done this once before with an FS60... and Matt rescued me then too. I didn't learn me nothin' obviously
Oh, she looks beau-ti-ful! I'll upload picture soon
The pimple on the side of her cheek is gone foreever
