Gossamer Gear Miniposa Backpack REVIEW

Aluminum stays that are 1/2 inch wide and 1/8 inch thick will fit in the sleeves and weigh around 5 oz. This aluminum bar stock was available at my local hardware store, and easy to cut with a hacksaw. Alluminum Arrow Shafts will only weigh around 2 oz., are bendable, and will fit as well. I wonder if I drilled a hole in the arrow shaft near the top of the pack, and inserted a large cotter pin parrallel with the back of the pack, would it keep the shaft from twisting? It might need a piece of plastic to protect the pack fabric and firm the pin up. Of course, GG has a suggestion on thier website of taking a coat hanger and bending it between the two shafts with notches in the ends of the shafts to keep them from twisting. That might be the easiest and lightest solution after all. I just got the pack and it seems great!-Scott
