There are a lot more folks on here that know more then I do —but I would strongly recommend that you start with a much lighter weight bow. Particularly since you have some issues with your arms or shoulders. My fall back is a 35# grizzly recurve (presently on loan to a good friend recovering from rotater cuff surgery)he used that for two weeks and know has my 49# shrew long bow. So he gets to try both before buying. I can tell you that he is in love with the longbow and I may not get it back. As you will discover in this forum weight of draw is insignificant to proper form and accuracy. And in Trad bow you don’t have any sights or let off devices its all you and the arrow.Don’t forget to check out T J’s book and Fred Asbell on the forums book list. Enjoy the journey.
