After trying several different back band set ups, I settled on Duane Strosaker’s arrangement, see his post linked below. I screw the attachment straps into the underside of the coaming shim stack and use 1/16 inch dia. bungee to attach the back to the bulkhead. The way I lace one length of bungee through the fairleads gives the bungee plenty of stretch to allow the back band to be adgusted forward or back without adjusting the bungee length. I do not install the cheek plates (as Duane does) because the 3 inch carved minicell foam seat provides all the lateral support I need to roll. I also use the Rapid Pulse standard backband linked on Duane's post.
