Yeah, Copperheads are not easy to come by. Might want to try something more economical for your first try. I would also suggest cleaning and prepping the surface of the bow limb with steel wool and wipe down with alcohol or acetone, being careful not to let the solvent get on any part of the bow but the back of your limb. If you first wet the skins and do a wet fit without glue (prior to prepping the back of the bow), then you can trim them to fit, which makes clean up, after you do glue, much easier. Good luck!
