I use the fiberglass fence post also with the 3/8 inch fuel line on the top. I keep mine at 46 inches in length. I join them together 3 1/2 inches from the top with a bolt. I wrap the legs with cloth camo tape. I cut the bolt to length. I mix up some JB weld. I put the JB weld in the fuel line to secure them to the sticks. I JB weld the nut, and the bottom of the shooting sticks to keep the tape from rolling up when I put the sticks into the ground. I can go prone to kneeling with these. I leave the fuel line looped at the top of the sticks, they make the sticks that much more steady.
