I was considering trying some carbon arrows and was confused on which size shaft to buy. I wanted to try the Gold Tips. I shoot a 48# recurve at 28". They offer several shaft sizes as follows. 1535 which has a spine of .600 and weighs 7.6g per inch. The others are 3555, spine .500, 8.6g per inch, 5575, .400 at 9.3 g perinch and lastly the 7595, .300 at 11g per inch. I was guessing to go with the 3555, .500 and 8.6 gr. per inch. but was unsure. Any help would be appreciated. I will mainly be using them for whitetail hunting with a 2 blade 125 gr. point.
