Almost every big smallie I've got a hold of this year has gotten off, I've had it happen quite a bit last season also.
I've had no problems with the smaller ones, and once in awhile I can land a nice one, but last week I had a huge one that might of been my PB rip the front treble hooks and the split ring right off my Whopper Plopper size 90. This river was calm and no more than 2 ft. deep at this spot.
And then, yesterday I'm doing a little wading in the river due to limited time, and I hook up on 4 big smallies in a 20 minutes span. I fought them, some longer than others depending on the drag, a couple of them I was able to even get them within reaching distance of me before they busted loose. I will say though that the smallies in this particular river are mean and fight very hard.
BTW, I'm mostly kayak fishing on 2 ft. deep rivers when fishing for smallies. I mostly use a WP size 90 & occasionally the 110, and a Squarebill, and it happens with both lures. My cranking rod is a custom Phenix X-10 and the reel is a SLX MGL 70 6.3.1. I've caught 95% of my fish on that combo this year and I've got a Conquest, Xtasy, and 4 Custom X-Rays.
I've tried loosening my drag and letting them tire themselves out and I've tried tighten it to power them in quickly.
I wasn't sure if I was sweep hooking to hard and creating a hole in the fish's mouth for the hook to slip out of, so I tried just reeling hard when I hooked up.
I was using brand new Gamakatsu Trebles on front and back yesterday of the WP I used, and just recently changed the hooks on my favorite Squarebill.
I'm almost sure it's something technical, but not exactly sure what. Maybe, I'm reeling too hard when they are running hard, it does seem like they are also running hard at first and it don't let up until they are spent. And, on top of that the water is 2 ft. deep or less, so they tend to jump out of the water multiple times and in a lot of case that's when they spit the lure and I lose them.
I guess what I'd like to know is about the best way to set my drag in these situations, how to handle fight the river smallies when they keep pulling hard, the best way to help prevent them from spitting lures, and any other advice you can give me. Thanks!
