To me...that is not enough leather to even begin to worry about.
Get that dude broke, and tie his head in the rafters. As long necked as he is, if you can keep his head up it isn't gonna be a problem at all.
The problem that I have with a neck sweat on a baby is what it does to his hair. You are talking about jackpot shows, and you are going to need all the hair you can get!
