I picked up a recurve at a yard sale recently. It's marked American Archery Oconto Falls, WIS. X-48, #2249, amo50, 50#@28". I took it to my local archery shop and they reccomended a 50" string. After putting it on they pulled the bow on a scale and it was about 50# @ 28". The brace height is about 8 1/4". I was told by someone else that this is too much and I need a shorter string to reduce the brace height. Any opinions?
