My main bow is a Ben Pearson Cougar recurve, center shot, 47 lbs at 28". My draw is 26" so my actual pull is around 43 lbs, figuring about 2 lbs per inch, as I saw a formula listed on 1 site or another. My wife has a 35 lb Bearcat recurve takedown. Importance of spine with center shot has long been a question of mine that I had not yet posted. It would seem less important with wrap around/deflection not being an issue, but arrow should still be sturdy enough to hold up to the thrust. My daughter's bow, OTOH, is not center shot & is much lighter, about 20 lbs. Anything too stiff will flop off to the left and be very hard to aim. At that weight, I would think very few arrows would be too light. Most storebought arrows were too heavy and flopped left. I made 1 arrow from a 1/4" dowel that shot fairly straight & fast. She lost it same day though. I made 3 others from dowels that she has not had a chance to try yet.
