I don’t know if i’m on the extreme side. I havent really though of it, because there is a few Sr players on the club that also use 41mm. What profile they’re on, i don’t know but after speaking to other coaches from other U13 teams on education days and so on, it seems as if we (our club) use shallower hollows than most other clubs on U13 level here.
Most seem to be on somwhere around 20-25mm on their U13 players.
