I went with the Bowtech Extreme because I want to start shooting 3d, the bow's got plenty of zip. My friend just bought a Mighty Might before I bought mine and I was impressed with it. I went with the Extreme because of the longer axle length and more speed with out going with a dually. I just didn't like that you could only get them with a 65% let off. I'm planning on shooting them with 70 grain tips. that may change after shooting them out of the bow.
I see that your an instructor, got any free tips?
