Bought both of my daughters Diamond Atomic bows. Oldest 8 has been shooting hers with fingers no peep and I took off the sight. Youngest 6 hasn't shot hers yet been to cold. My question is should I add a peep and get them shooting with a release and add back on the sight?. I didn't have a bow at their age so I have no reference. Any insight or here is what I did suggestions would be much appreciated.
