I've been having trouble with my knots also and I tied up this knot yesterday and boy it really holds and doesn't come loose. So I think that I will switch to this one. I've been using the weaver knot but you end up using to much leader when you tie it up. the tag end is usuall about 2" long and after you swap a few flies you end up having to add more tippet material. So a change is in order.
