As Quik said I would if I KNEW for certain that the buck in question was in the area I hunt and that I had a fair idea of what he is up to (i.e. bedding area, staging areas, nearby travel corridores, etc.). If that were the case then yes I'd be passing up the shooter to try to get the bigger guy.

After all, I like to challenge myself to take that next step. That's what it's all about for me.
