Strike 3 those are your composite choices for this upcoming season if you are talking about high school, not your only choices unless the state you play in has decided to go to BBCOR for 2010/2011.
I believe you could still use a bat that has a composite handle for 2011 season. Players could still use a bat from last season or buy a bat that is not on the list you provided as long as it does not have a composite barrel. I may be wrong but that is how I read all of this.
