So I mearsured how I draw and found I pull the arrow about 26 inches back. Its a montana 55 # with stock strings and I plan to use 125 grain heads. I am thinking about getting some rose city bear arrows and before I drop alot of money I am trying to get my research in.
At your draw, you'll be drawing about 50#. Bow is cut a bit proud of center I believe. Don't know what kind of string you have, low stretch or dacron. If you cut your arrows to 27 inches back of point (28 inches overall to leave room for the point taper) and go with a 125 grain point, 50-55# should work for you. 5# one way or the other would probably also work. You could start with a test kit. If you buy from Rose City, see what they recommend.
I put togather some 3 rivers cut at 29 at 50-55 and they shoot perfect. I guess I may be over thinking this but 150 plus for arrows kinda makes me over think things :biglaugh:
Rose City's online order form for their Bear series arrows doesn't allow you to request a spine range or arrow length and doesn't even specify bow weight. They ask for shaft diameter and draw length for a particular arrow model # so I don't see how they can determine your actual need from those specs. I guess you would need to talk to them to place an order.
as you fill it out addtional questions come up. Try it and you will see.
