I used the Red Phillips knot several times this weekend. It is indeed both quick to tie and small. (I did learn that when snugging up the uni knot in the braid to pull on the standing line first. If you pull the tag end, you risk sliding the uni knot off the short tail of doubled mono, thus ruining the knot. Had to cut and start over the first time I tried it.)
As always, you need a sharp scissors or nail clippers to trim the braid tag end. A knife leaves a frayed, ugly end.
I had earlier lost a snagged lure and leader when my uni-uni knot broke under heavy pressure. No such problem with the Red Phillips, but I never had a hard snag with that setup, either. I replaced a buddy's leader with the RP knot, and the second tying attempt went much smoother. It's a keeper in my bag of knot tricks.
