I think I have some of the SX files, but I don't think I've used them
yet. My motor was set close (but not exact) to the rotary
specifications. The Tulsa guy did come into our office. He didn't say
anything about a circumferential motion.
I've had nothing but trouble with my apex locator (a Bingo, and it
wasn't cheap.
Glad to hear I'm not the only fogie still using cold GP.
