I used to do that all the time until i read that 8 carrier braid doesnt like getting twisted like that and weakens the join...seeing as i liked to use YGK X8 jigman....it was time to learn the PR.......but i never had a failure........
the pros for me
1.I could tie a bimini and re leader quicker with above...than tying a PR knot....one skip turned around and couldnt believe how quick i was rigged up.
2.At the end of the day...if the leader was low...i could undo the leader and put a new leader on and leave the bimini double there.
3.I had bimini doubles that had been on for some time and i never re tied them(never failed)
4.No bubble trail like you can get from a PR knot(couda will attack the knot and you lose everything.)
The cons......
1....suffix wind ons were 17 dollars each for 150 pound but i never had one fail.
2.Tying a PR knot or FG is far more economical with your own leader.
This system works well for jigging.....is great when couda are around and good until you learn an FG knot or PR......I jigged with this set up for probably 3 years before i finally learnt the PR......tying a short Pr can combat the bubble trail somewhat.
Anyone of these 3 will do the job

.......But you must feel confident in your system.....Practice your knots.
