Ben,Nice to see you guys still catching your limits trolling.Most of the charters using big boards run the TT40s with spoons still.They have been very effective combo to run and have caught a ton of walleye.The TT40s pull to hard with our inline boards.That is why we run our spoons off the dipseys.I believe the turbulence created by the dipsey and TT40 attract the fish.I have some TT30 that work behind my inline boards and do run them with spoons at certain times of year.But,the dipseys are much easier and faster to use than an inline board.
