I'm thinking about making the switch from Carbon to Alum arrows. I did the arrow selector chart on Easton website and they recommend 340, 2219, 2315 or the 2413. I found a chart (maybe an older version?) and according to that I would need a 400, 2117, 2215, 2216 or 2314. My bow is a 2022 Bear Species (IBO 320) set to 60lbs and 27" draw. I'm using 27" arrows with 100 grain broadheads. I would prefer to go with a lighter alum since I'm not shooting a lot of weight and don't have a speed bow. For guys with similar setups which alum arrows are you using?
