Ha, yeh Texas don't mix well with anything really, i kinda put them in the same category as Midas, Red Devils, Viejas and Jags etc.
I have pretty much given up mixing Centrals now, and only ever mix south's with souths because they don't interbreed (unless in the same genus) and are less aggressive.
Of course you do get exceptions, and Texas are beautiful, espech the the Carpintis (green Texas) variety's like Escondido.
Wasn't the Texas you have the ones you were sold as Blue Acaras a few months back?
