How about a good strong broom handle ? Then after you shoot it everything could go in the garbage where it belongs. I only say that because it looks like sh!! - period. Now if you would have made some wood grips and stock that attached it would be a different story.
On a different note when my grand daughter got old enough to hunt, her step dad, a really big time deer hunter, bought her a compound bow and a inline MLer. I never said a word, but she wouldn't use them. Instead she borrowed one of my longbows and a T/C 54 cal gun. She's shot deer with both. I gave her the Brian Ferguson bow and she'll get one of my home made MLers anytime she ask.
