Another Spine question...

[youngarcher1]

I just received my new Beeler tracker and i love it! but i want to start shooting some carbons out of it specifically CX's heritage except i dont know what spine. The bow's 59 @ 27, im thinking the 250's with a high FOC? . i want to eventually go for about a 600 grain arrow and maintain a gpp of 10. Stu's calculator doesnt seem to want to work for me. Any input is much welcomed!

Thanks, Morgan

250s will work at around 30 in. long and 200-250 up front .
