Last week I had my 16 year old daughters Synergy 33/22 (which feels slightly endloaded) in the bag. I was coaching my 12u team made of all but one 11 year old. One of them asked to use the bat and to my surprise 3 of them asked to use it. They successfully used and easily handled the bat. I encourage dad's who are worried about bat weight and wind up buying a -12 or even -13 bat to work on mechanics and connection and not be afraid of something a little heavier (like -10) and a little longer. I think all of my 11 y/o are swinging 32/22's. We have a nice 2012 DeMarini CF5 32/21 the kids seem to love as well but in general the kids that were swinging 30" bats just 2 months ago are handling these bigger bats just fine.
