I built the .385 and like it. I built it to 34″ so it would fit in my rod bag. I would build it longer now that I have a box for my rods. This guy guides lake trout in Northern MN and recommends this type of rod.
“Rods: 42-44 inch spinning rods. Pictured is the Gary Roach Mr. Walleye 42 Heavy, which is designed as a walleye rod but is the perfect lake trout jigging utensil. We also use HT Sapphire Ice 42 MH. The rods run $30-40, so they don’t break the bank. I have several custom 45-52″ spinning and bait casting laker rods, but I can tell you they don’t help you catch more fish, and the fight is the same on the mass produced rods. Your rod must be long and limber enough to keep a deep bend in it. Rigid rods lose lakers!”
Gary’s rod building in Anoka, MN helped me build it and walked me through the process and recommended spacing for guides and such. He has it set up in his basement and it was nice to have help and the proper equipment.
