I run with them and without them. In OH I can only use two rods when solo. Everything solo is harder. Unless I’m running open water, I usually only use one board on the side closest to shore so I can keep the boat out a ways. The other side is usually a down rod with/without a short line. On very steep banks I’ll run both on one side. The board keeps them separated.
On the board I’ll put a small Stay-Loc snap in the rear position that hangs up on the leader swivel when the front clip is released. That way I don’t need to worry about the board getting away from me and I only have one clip to release.
It’s not for everyone but it seems to work for me.
