I've never named a compound. I figure they came with their name stamped on 'em anyway, so it'd be redundant.
Had a longbow once I called 'Thumper.' 120 pounds draw, shooting 2419's. It hit what I was shooting at really hard, and it had just as much handshock at my end. It was a Thumper at both ends.[&:]
My all time favorite recurve was a Brackenbury Legend. I named it Mojo, because that's what it had. Weren't many misses built into that bow.
