RE: How many have a back up bow?
I call them two 'active' bows. I practice with both at the same time so that my confidence is good with both. I'm not sure which one I'll hunt with first, but if an issue occurs with one, the other is right there for use. They both shoot the same arrows and almost the same accessories so that adds to the consistency.
If two break in the field at the same time, I'll just go home as it was not meant to be!!!
