RE: MAJOR BUCK!!!!!! Dilema!!!
I wish I had your problem. Go w/ your gut.
In my opinion, it depends on the outlay of the land and where you plan on hunting. If your chosen spot doesn't really feel like a good bow spot, take the rifle. There's nothing wrong w/ shooting a deer w/ a gun...but with this being the bow forum and you asking for some opinions on it, I have a good idea which way you're leaning.
Good luck to ya in whatever you decide!
