I was looking for a one-piece -9 a month ago, tired of cracked Xeno's. Couldn't find the bats at all then. Local store offered to take a deposit, sight unseen.
FWIW....
DD's team has this bat in 32/22, DD has a Stealth in 33/23. While it is a good bat, she gets much more out of the Stealth. I can't quantify it with numbers, but she has never hit the ball as far, and with as much energy with the Synergy, compared to the Stealth. Both bats were purchased about the same time, so she had not gotten used to either of them.
With that said, I don't have anything bad to say, just a quick comparison for reference in our case.
My daughter is using that bat this fall. Her DeMarini Vendetta was flat from the time it came out of the box. She is hitting better and further with the Easton 30/20. Her teammate used a '12 Synergy last season in 10U and hit a monster homerun over the 200Ft left field fence at the Branson RecPlex about 10 ft. We're believers! I was able to pick it up for under $150 on sale at softballsavings.com.
I got on Eastons website looking at the 2013 Models and dont remember seeing it. But i was looking at the new stealths!! i must admit, i stalk bat manufactures websites!!!lol
