Jeff, I know exactly what you mean. I recently traded in the bow that killed my buck this past fall, and it was a bit emotional actually. I really hated to see the ole girl go....BUT, that didn't take too terribly long to overcome....
Now I do, however, still have the bow I killed my first deer with. That one I will never part with, a ProLine Riptide. 41" ATA w/ recurve limbs. Sounds like a friggin shotgun goin off, but fast and hits like a hammer.
