I also worry when someone starts measuring weight in "ounces", particularly as it relates to the 6U class. A few years ago we had some members of this board comparing the weight of singlets in "ounces" from one brand to another. I see many problems ahead for you and your youth wrestler if you are worrying about "ounces". The reason that there are so many weight groups, so close together at the younger ages, is so nobody worries about "ounces"!
