I'm not a big lake trout guy but I keep getting better. My focus has largely been on crank baits for lakers but I have pulled a dipsy/flutter spoon for lakers with no tangling problems.

I think you could rather easily put a flasher out if you wanted to. Use lots of ball bearing swivels at all junctions and keep everything "in line" with shortish leads. Remember you will have to land the fish and if your running 4' leads things could get dicey.

Rod holders become very important IMO with all specialty type trolling scenarios. As well as using braid and conventional tackle (bait casters). For example, I can get my track going with no real need to go balls to the walls, have my rod in the holder with set up trailing along barely in the water and then loosen my star drag to the point line feeds out in a nice steady controlled flow.......no opening the bail of a spinning outfit while loads of line send a sinker, flasher etc. etc. plummeting and spinning towards the bottom. Can you say "tangles"? Can you say "hassle"?

If trolling is your "thing" while in canoe country (certainly is for me) then there is no substitute for a good rod holder and conventional reels (preferably a line counter).
