I have a mac and I'm unable to download this program. Is there a similar program that would be compatible with my set up? I recently changed my draw length and need new arrows, I have a Hoyt Katera 30" 70 lbs. and a GTO 30" 70 lbs. on order. I need some help choosing length, brand and spine. I will use a 100 gr. head and blazer vanes. This arrow will be for hunting. I was thinking GT Pro Hunters 7595 cut at 29.5", but not sure if this would be best.
Thank you,
Craig
