I use mostly #2 and #1 dropshot hooks. I use #17 test mono as it lays out straighter and you will get less harness twisting. If you stick with 10 or 12lb test you can us smaller hooks since to snell a lot of hooks the eyelet is not large enough to double 17 or 20lb test line thru. Yes, when required I will add one of my stinger hooks to make the rig a 3 hook harness but that is very rare. I'd rather figure out a better method staying with the 2 hook as that stinger just makes you take that little fish off every time, and you still have to replace the worm. Sometimes it works to put 1/2 to 1/3 of a crawler ( depending on size) on the front hook and put a 4 inch rubber worm on the back hook so it looks like one long worm, the trash fish typically don't like the rubber worm, they nip then let go but walleye will still engulf the whole thing.
