Well last trip out east I hooked a fish speed trolling and slowed down in reverse and forgot the motor was on and cut my 300 grain 26 ft. head line in half (ouch) now I am looking to replace it with another heavy sinker. I love the 300 grain head for trolling. my friend Derek came on a trip and had bought a 450 grain 24 ft. head line for trolling and actually did better with hook-ups because he was deeper when speed trolling! what I'm wondering is do any of you use loop to loop heads for trolling trout? like a 20 or 30 ft. 300 to 500 grain head with running line on the reel? what I'm thinking is the running line would be thinner anyway and let these heavy tips sink even better. I know this is kinda like the spey set-up but would only be used for trolling not casting hardly at all but to help get the line out with a 6 wt. I have 7 and 8 wts. but do not use them for trout. I could have one spool lined with backing and running line and possibly tips in the 300 and 400 grain weights to loop on fast. seems I could do this pretty cheap just don't really know how to go about it. Thanks for any advice!!!
