Why not screw in a suitable length bankstick adjacent to the rods on the downstream side? That's what I('d) do. Doesn't matter whether they're 1,3,5, or any number of inches above the level of the rod, they're purely to stop it going sideways and you're going to be picking it up either straight, or in the opposite direction, depending on whether you're bolt-rigged or running.
I find setting your baitrunner so that it gives line just before the tip would be pointing at the fish coupled with decent "butt-grips" is more than sufficient. Tbh I've only ever used the banksticks when carp are possible on the river.
Edit: I use Delkims.
