There is not
The 2012 Exo Grid (BBCOR) is the only legal college exo bat.
I have an exo grid and a Triton the exo grid has more pop but the Triton has a bigger sweet spot so u wont pop out as much with the Triton
The White, White (Air), and Red seem to be the best 3.
a techzilla depends... an exo or stealth is good if the Anderson is too heavy, but a demarini works too Combat B1 B2 B3 or Exo Grid 2010 but i say b3 all the way
exo
The Triton isn't a bad bat, and it is $100 cheaper. The Exo is a better quality, and has more pop. I would Go with the Exo.
the 2011 tpx exogrid has already came out
Nike Aero Fuse Cx2
Easton's power brigade series, the Easton omens, demarini cf4+5, tpx exo grid 2 and combat b1/2/3/4
the white exo is and has been the best exo that tpx has made so far. i have used all of them and i currently have the white one. it has much more pop than any of the other exo grids. that's the only difference.
