I only need as many as I can hang on my current bow racks...as they stay nearly full...so for me the number is 16....but 5 are old vintage Browning classics, 1 was gifted to me by Joe Mattingly, 1 was my very first traditional bow I got from Owen Jefferies when he had his shop on Pepper Street in Columbia SC and I was stationed in Sumter SC.... Really the only ones I would consider getting rid of is one of my Brownings...a mint condition Cobra II.....and maybe my Habu from 1999 unless I get lower weight limbs which if Chris wants to charge current prices on that old limb design will never happen as they are as much as I paid for the whole bow back then. LOL I have two hickory staves to make into a selfbow....maybe one more glass bow and anything else will be selfbows once I start making them for myself.
