when jigging for tuna, how should the leader to the jig be rigged?
should a swivel be used? how long of a flurocarbon leader and of what pound test should be used? how do i stop the break-offs due to wahoo? and how should they be fished?
Well, Out of Cape May I really don't have a problem with Wahoo's! But I use Power Pro #50 with a Fluro leader of #60 no more than 36" and the knot I use is a double Uni and I have never had a problem with that knot as of yet! There is basically 2 ways to jig a diamond jig, some guys really jig the tip up and down, by that I mean the rop tip is almost touching the water and jig it up a good 3 feet or more depending on the length of the rod. I use the other technique which is a very little movement of the rod tip. By that I mean I jiggle the tip no more than 6" just to make the jig dance a little down there and that method seams to work really well!
I approach it a little differently than striper myself. I use a bimini in the braid and a bristol to connect the flouro to the bimini loop. I start out with about 15-20 feet of flouro leader; not because that much is needed, but because i can cut chaffed leader liberally and retie the jigs without having to worry about line to line connections on the water.
As for the wahoos, you can crimp about 8 inches of 49 strand to the jig and then to a swivel, however you are going to significantly reduce your bites from the tunafish in most circumstances.
