You can put as much line as you want behind the board but the more line out behind the board means you may/will have to remove the board to get the fish to the boat or have a long handled net. I use 8-10' long rods so if I have to put more line out behind the board than the length of the rod, I'll just long line as it's easier for me that way.

I fished Tellico on Saturday as well, and I pulled one board just messing around with something for a little bit, but all the fish I saw were too deep to use boards IMO, so I just long lined over creek channels/beds.
Thanks for the input. That is basically what I was trying to say, but having a hard time wording it. Good ideas from you and footballcoach. If deeper than a few feet, longline. Thanks guys!
