BBJ, you can ask a hundred people that question and get a hundred different answers. Those bows mention are all capable a bringing down an elk or any other big game in North America. Shoot all 3 and find out which one feels the most comfortable and less vibration, length of bow and weather you will shoot fingers or release? Make sure that someone fits you to the bow and that the arrows are matched with the bow weight. I would not recommend buying a used bow at the pawn but cheque out some dealers or archery clubs there in Lewistown and get started out right. Also keep in mind that Montana requires a Bowhunters education class before you get a bowhunters tag. ( In which I am a cerified instructor)
I shoot a 63# TRX compound using 2314 aluminum shafts with 125 grain thunderhead broadhead and use fingers. I want to buy a black widow recurve for next year but they want $1,000, OUCH!!! Good luck and if I can help out in any way let me know. Bobby
