A great experiment and I sit here envious of you having the 4 different choices available! I harvested a muley this year that was very good but different from the SE Ohio whitetail I still had in the freezer... but I got to say the 2.5 year old bull elk I got in the same area as the muley tastes even better. I am very much looking to take the young cow elk this year to see the taste difference. I am still looking to get the speed goat this year as many tell me it is even better!?!?!
