Everyone wants to skin their first bow. Like Pat said, wait until you are satisfied with a bow before committing a good pair of skins to it. Shoot it a bunch, recheck the tiller, make sure there are no hinges or tillering problems, shoot the bow for a while more. If you find the bow to be top notch, proceed with the skins.
I used a nice pair of timber rattlers on about my 3rd bow, a dog of a boat paddle hickory bow that would jar your toe nails off with hand shock. Sure wish I had saved those skins for a better bow.
