The price of eels are starting to catch up.. They are now over 2 dollars each.. I used to buy them 8-10 each time.. Now i buy them by the pound.. I'm also able to pick out the one's i want.. Being able to pick them out and my own eel tank has made it a little easier on the wallet..
I've caught tuna on a 12" sluggo, that's the only time I've thrown them. I run about 8" of pencil lead through it extra heave-ability and match it with a 9/0 Hogy grip hook. With that combination I can still work it on or right under the surface.
I've used them double rigged with and without weights and the results haven't been that good. They are fairly stiff so unlike the hogy there is little motion. Kind of like a big needlefish. I've had much better luck with the 9" either sigle or double hooks.
