I have a Affinity that I let my daughter use last season. She is 28 but has no hunting experience and wanted to try it. I was using a Carlson Long Beard .568 choke and Winchester Long Beard 3" #5's. The pattern was extremely tight. I was at Wal-Mart and they had Winchester Double X 3" #4's on clearance. So I tried a box of those and the pattern was perfect for a newbie. At 30 yards the pattern was even but not too tight, exactly what I wanted for her. She did not get an opportunity but I was confident that the set up was forgiving enough for a first time hunter.
This set up is not as sexy as many you hear about on this forum but I was happy with it and my daughter was too. Good luck to your daughter and thank you for taking her hunting.
