With18 points and a desire for a muzzy tag, the sky is ALMOST a the limit for you. Unless 18+ pointers jump pools from 2014, you'll draw Beaver, Boulder, and Pahvant. You're a year or two away from the bonus pools on Monroe and San Juan.
Are you familiar with any of the units you listed? If so, choose that one. If not, what would be easiest for you to spend time on this summer? They all produce huge bulls regularly. All would be fun rut hunts with a muzzy. Pick one, I don't think you can go wrong.
