I am very new to recurves and I purchased one from my neighbor who knows about the same about them as I do, which is nothing. It is a 58" 45-50 lb. and it doesnt have a string I would like to order one but I dont know what size to get. So, can someone tell me how to figure this out, or what do you figure in to come up with the proper string length. And, is there anything on the net that can guide me thru the process of starting out with a recurve. any info would be great.
