Default Check my optimal spine

Can some check my build to see if Im with the optimal spine range, my computer is down and cant run my OT2 software.
Gold tip X cutter 7.8 grains per in at 28.5 (222 grains)
Nocks, bushings, and vanes (5, 17, 18 (3x6))
150 points and 30 grains behind it (180 point weight
60 lbs at 30.25 draw and 18 grains on the string
Should be around 440 grains total to get me around 280 FPS for ASA

Thanks for any help and Merry Christmas

A 350 or even better 340 spine will tune very well for you based off your variables. I see the optimal dynamic spine around .336.
