I knew my 2117's were way underspined for what i am shooting...70 lbs 31 inch arrows at about a 29" draw 115 gr. BH.
I know by the charts ishould be usinga .300 spined arrow even at 30" which is what i had the arrows cut to but I couldnt find them in a carbon arrow that was within my price range.So I got the Beman 340 ics venture cut to 30 inches and i do plan to go to a 100 gr BH from the 115 gr BH.
By the charts i would only have to drop 4 lbs off my draw weight with the 100 gr BH to actually be within the spine or 7 lbs with the 115 gr BH.
my question is...is 4 lbs really worth the time to back off the bow or is this close enough not to worry?
