Hell no that's not greedy! It's your hunt, shoot what you want. Don't shoot at something that doesn't make you happy at the time. I passed on a mid 120's buck last Thursday. I'm not greedy, I know I've got bigger and I'm willing to push the luck and see what happens. If I go without a buck again, what's new!
Good luck! I hope you get what your after. That's why your hunting to get what
you want.
