I have a young shooter who is convinced he must shoot a 20ga due to his size, I had him try the team gun a12ga which he shot just as good with no noticeable recoil issues and he shot it better, talked to him and his parents about the advantage of a 12ga pertaining to ammo (cost and felt recoil) and weight.

I believe his friend may have alot to do with his thinking(peer influence)

, I hear the friend on the sidelines telling him a 20ga is better for him because he is small.

Any ideas how to convince him to go to a 12ga.
