Kelly had a spine chart for aluminum arrows and traditional bows. Does anyone know where I can access that information? Thanks.

I just took a look at the Easton spine chart for aluminum arrow setups. I can use the spine chart, but since I'm shooting two recurve bows at different poundages, the chart is spot on for me as long as I use the "longbow" recommendation. It's way off for me using the recurve recommendation.

Using Stu Miller's calculator program, it mirrors the Easton spine chart "longbow" recommendation for me.

But, on both of my bows, the brace height is different for each one of them.
Blacktail TD Recurve: 66", 42# @ 30". Arrow: 32", 2212. PW: 75 Grains. AW: 421 Grains. GPP: 10.02
Blacktail TD Recurve: 66", 37# @ 30". Arrow: 32", 2212. PW: 75 Grains. AW: 421 Grains. GPP: 11.37
