I have both Acoustic and Acoustic Carbon.
Despite being similar they play very differently.
AC has the touch of Acoustic and very high dwell for a carbon blade. For a carbon blade it has gianormous control and feeling and a very loud sound.
The Acoustic is more of a looper blade. High dwell, medium high throw, excellent feeling and touch and lot of vibrations, but it feels good.
My recomendation is if you have the budget and are mainly topspiner or looper go for Acoustic Carbon or Acoustic respectively.
Now, if you are opne to recomendations, Avalox P500 or Nittaku Avalox P500, Xiom Offensive S are awesome blades with tons of feeling and similar playability to Acoustic.
Oh, and both of mine are Large handle too. 86gr AC 88gr Acoustic.
