After trying the ring buckles, only to slide down and "embrace mother earth" I read about the cinch buckles. A co-worker was enlisted to order some online. Ordered from onrope 1 on friday. figured it'd take at least a week to get 'em. Shock and aw! they were in the mailbox monday! Sat down and cooked up some adaptators for the NX150, and headed for the back yard for a test run.
Stunning. These things are fast to set up, and they actually work! I bounced around trying to force the issue, but to no avail. These things stay right where you put 'em! Thank you folks for spreading the word, it really is informative reading HF.
