leader knot questions

[Crankbait]

Ok so here’s the 2nd part to my love of braid question. Even though I use 6lb for cranking which is incredible thin I'm still was always concerned about the fish seeing my line. My buddy tried to get me to try the double uni to add a leader but I didn’t have great success with the knot.....it broke when i pulled it. I’ve been in florida fishing snook and redfish and had to put a leader on my power pro line. I’ve been tying the surgeons knot 20lb power pro with 20 lbs seaguar red label fluorocarbon with incredible results. Never broke. i i was doing some hard hooksets when fishing the fluke! Getting ready to head back to NC and my bass fishing and try this knot out. I’ve been looking at modified Albright and the double Albright knot as well. I want a knot that’s strong but also be able to run through my guides. When I was fishing the snook and redfish my leader was usually no more than 18”-24” and the knot never went through my guides because I swivel cast so much. But now I’m thinking of 2’-3’ foot leader for my cranking. So I want to know what you guys use (knot wise) and also what your preferred fluorocarbon is for a leader?
