we’d already seen this same knot demonstrated by my buddy Scott Loudon two and a half years ago but since this newer video just came out i thought a little refresher wouldn’t hurt.
having used it quasi-exclusively when using a loop knot since seeing Scott’s tutorial, i’ll not go into breaking strain figures as i’ve no idea and don’t really care… but i haven’t had a single knot failure since.
no, i haven’t caught any monstrously huge fresh or saltwater fish in that period but i have caught quite a number of nice sized trout (50-60cm) on very fine 6-7-8X tippet. we know the knot was originally adapted to fish big saltwater fish on big tippets so, if it holds equally well on the finest hook eye diameters and mono then it’s a real universal knot.
besides, most of us know how to tie the Perfection Loop so in actuality, there isn’t anything to learn. give it a try !
as noted on the first post’s comments (Scotty’s link above)- “if instead of grabbing the fly and standing line in the last step, you pull on the tag of the tippet, you will get a much smaller loop.”
as long as it isn’t the tag leg that’s being used to permanently seat the knot (just use that to make the loop smaller and seat it normally) that’s spot on but isn’t as far as i can tell of any real importance when attaching big flies for predator fish but on the other hand, a real bonus when using this knot for smaller, typical ‘trout-type’ flies such as dries, wets and nymphs.
yes, a free-swinging fly isn’t just about allowing the fly to jiggle more when its being pulled but also the hinge effect of an open loop knot on smaller flies means a little less leader-induced drag when we’re trying to achieve drag-free drifts. a nice little bonus.
