hmmm....i dont know bout that one. the arrow is the most important part of your set up, you need the weight of a fiberglass shaft to penetrate the water. if your talkin about drilling a alum shaft behind the broadhead, i dont think it would be too safe, weakening the arrow and all. ive seen some shoot at fish close on the shoreline, with no line, and run to grab the pinned fish, never tried it though. i would say the fishing arrow is the only thing you dont want to make up.
