yes i know that..... i was speaking in reference to the content of the OP,....(of using a loop on your string). it is, after all, pretty much the status quo these days, regardless of whether the methodology it is "correct" or not. i doubt someone saying, "calipers aren't designed to be used with a loop", is going to change the polarity any at all. a statement like that might have had some weight some 25 years ago, but the calipers' use is far too ingrained to change it now-a-days. i don't care for caliper style releases,...never have... and i never used one.....that doesn't mean i don't know all about them. i was shooting for quite a few years already when they first came out.
