I wish this thread was published two years ago when i started using dipsys. Would have really helped out, great info here- this should almost be a sticky.
About the only thing i could say is that it's best to use braid on your dipsys to the diver- then snubber and a floro leader. I troll for salmon on Lake Michigan and alot of guys use wire for their deep, inside dipsy. I will have two wire divers in use myself this upcoming year. Not only do they run a tad deeper but the wire is supposed to give off a frequency that attracts fish.
