Couple things...run braided (my pref is 30# Power Pro) it helps trip those releases vs stretchy mono.
Not in the Great lakes you don't want to. The spiny fleas will stick to the braid pretty bad. Wire or 30# mono to avoid the fleas in these parts....
One more thing... as long as you're fishing for walleye you won't need one, but if you go for any hard hitters.. like salmon or steelhead.. you may want to put a "snubber" behind your dipsy to absorb the initial hit. I know Castaway doesn't, but I use them on Erie for those hog walleye... Plus we get those pesky steelies bothering us as well! Good Fishing, Sluggo (Chris)
Sluggo...after a triple dipsie break off when we hit a school of steelies, I've learned my lesson.
