No, I'm right eye domonant and a right hand shooter. I think Alpha Capo had it right. The change forced me to concentrate more. I had gotten complacent with my practice. It was to the point that I was flinging arrows and thats it. I have since gone back to shooting with both eyes open and I am focusing on the shot. I find that I shoot better now as long as I focus on what I'm doing. If my mind starts to wander its time to put the bow up until tomorrow.
