I mostly bank fish, and where I'm located there are a LOT of northern pike. If I throw any topwater or horizontal presentation (inline spinner, spinner bait, chatter bait, etc) and depending on the time of year, I am as likely to catch a toothy critter as a bass. In the past I used wire leaders to protect against bite offs, but I find even the smaller gauge leaders can foul up the lure action--especially prop baits--since the wire leaders virtually all have a swivel (to connect to main line) and a snap (to connect to the lure).
I got a spool of 50# fluorocarbon leader on sale and have been using that instead of wire. I like that I can tie direct, which is great for spinner baits and prop baits. However, the fluoro is very thick and stiff, which makes tying knots a bit challenging. I am also not sure the best knot to use to connect the leader to my main line, which is usually 15# or 20# mono or 20# braid, depending on my combo. (I am using more mono these days than braid for some reason.) The difference in diameter between even 20# mono and 50# fluoro is significant.
I've experimented with using a swivel to connect main to leader, which is ok, but I would prefer to use a line-to-line knot. I usually use an alberto knot to connect braid (main) to lighter fluoro (leader). I am not sure this would work with mono (main) and much thicker leader. Also, I don't know if an albert knot is recommended at all for use with a mono main line.
Any suggestions for knot to connect lines of very different size, when the lines are mono and fluoro? I suppose with 50# leader, no matter what knot I use it's going to be big and clunk around the line guides, so I'll need to keep the leader short.
