So should be 15O - 15 or Over. look at Baseball - 15U is 15 and under - you can't be 15 before a certain date. So older 15 year olds need to move up. Not sure what is the best way but I think the issue is what people understand or the consistancey in tournement requirments. I've been at tournements like most have where the expectation is thar your kids will be playing their grade age to see them walking onto fields with kids just having shaved before the game.
