Katie,
My daughter has Mike's first prototype "Pup" and it is right handed. We had tested her early at age 3 and we thought she showed right eye dominant. Later at age five she was closing her right eye and laying her head over the stock to shoot her .22 cal chipmunk. We retested her and she was a very positive left eye dominant. We talked to out eye doctor about it and he said that at the early age we tested her the first time, her brain had probably not developed a strong dominance. So we called Mike and ordered a new lefty "Pup". Mike was going to swap us even up for the righty, but you should have see nthe crocodile tears, when I told her we were sending her bow back. It was pretty sad. We ended up ponying up the money for a new one and just kept the righty. Worked at pretty good actually. When ever she has a friend over, we have an extra bow, plus one day she may have a right hand child she wants to pass it along to. I am left handed and my wife is left eye dominate, so it is working out pretty good. Take care and keep your family shooting!
