If a new guy gets nervous cause of tying knots then you`re in the wrong biz, the majority of rigging in a take down is all all about knowing knots & its clear that the dinosaur that started this thread is only worried about someone being faster on a cheaper device read some of his earlier posts, problem is when one gets too old to climb & properly teach they wanna resort to something like this & then that same nutpump will be yelling up at the guy telling him " no, tie it there, no wrong knot, no, no,no...faster,faster" all the while thinking the guy aloft will be safer cause GOLLY he doesnt need to know how to tie his friction hitch..before you could get the car up to 100 you had to drive at 25mph, starting out with these gizmos & not learning some of the traditional ways first will handicap you more than help you!!
You got alot of nerve! wantin to teach a newb as you suggest? im thinking the metamucil & stool softners has affected what lil brain you have!!!
