For your setup, I would have to recommend fixed blade broadheads. You could probably get away with well-tuned mechs, but to be safe, stick with fixed. Infact cut-on contact might be best for those Michigan brutes you will be hunting.
I wouldrecommend Magnus 4-blade 100gr. stingers, or MagnusII 2 blade 100 gr. screw-ins.
Also, as was mentioned slick-tricks are good.
And dont overlook, Thunderheads, Muzzys, and Montecs!
Now you know what to look for, so go out and pick up a pack or two. Dont forget to set a few aside for practice, and keep a few razor sharp for the moment of truth. Good luck to you---Matt
