Would this bow be a good first bow for someone looking to get into instinctive shooting? Will the 50# version have enough power to kill a deer humanely? Also, I'm right handed but left eye dominant. I currently shoot a left handed compound bow... Should I get the "right hand" version or the "right or left hand" version? And how can a bow come in a "right or left hand" version?
