I switched to braid to get rid of the twists and tangles on my spinning reel. I love it, but I don't love bass fishing enough to do the gymnastics required to tie and FG knot. The double uni knot is bulky in the rod guides and I feel like the fluoro side hitting the guides every cast is going to weaken it.
I am primaily bass fish , I used a double Uni for a long time and never had a problem. But switched about a year ago to a alberto knot , it is cery simple once you do it a few times and I am older , watch a video and now that is my braid to leader . The important thing with any knot is to cinch it fully , the connection knots that is important
