Well I bit the bullet and ordered the red/black TPU-X's which are the new version. So we'll see how it goes.
While I'd like to have stayed dexter, the 9's are new, we don't really know if there are any bugs in them, they only come with one sole and they cost more.
The tpux's have been updated, come with extra soles and are cheaper which saved me enough money to pay for two nights of bowling.
