58" bow will be fine. I use 33" (raw) shafting to make arrows and leave it at that length. Look for an old Bear Grizzly or Black Bear. The ugly colored ones go pretty cheap. Make sure it has silk screened logos and not decals, some of the early ones were made without a lot of research. You can not beat the way a Bear was manufactured in the late 50's and early 60's. I would be afraid to over draw (32") most other bows the way I do my Bear.
