Any reason why the 2 3/4 barrel isn't as big as the 2 3/4 barrel on the rawlings quatro? My son had a quatro & moved up in weight from -10 to a -5 & being that quatro doesn't make a -5 he went with the cat 8 being that it is balanced & says its a 2 3/4 barrel but after comparing them, its apparent that the quatro has a bigger barrel. Why is this?
