Hi Rob, when you say 'for every inch over 28', do you mean draw length or arrow length? And does it work the other way round - do you need to subtract if under 28"?
I will soon have a
flatbow
which will be 38# at my
draw length of 26" (this is the AMO 'true draw length' - from nock groove to pivot point, i.e. inside of the grip.) The
arrow length will be 1.5-2" longer, so you could say 28".
Bearing in mind it's a flatbow, so almost centre-cut, and the string is 8125, what would your formula suggest? I make it 48# spine (?).. And since shafts are sold in spine bands, does that mean trying the 45-50lb band?
The bowyer suggested 45# spine arrows (but again - which band?) and 75gn points...
Thanks for any advice!
