[Tango-L] Breaking the "paso basico."

['Mash]

I am getting frustrated with myself at the moment as I have discovered my first nasty Tango habit. 

I have found that when I am nervous my mind blanks itself of any variation in steps and defaults to the "paso basico."
The worst thing about this is that I automatically resolve on eight totally ruining flow of the dance. I really wish I never learnt the damn pattern as I am really struggling to break out of it. 

The first thing I am trying to do to break this is to lead an "americana" (I believe that is what it is called when you resolve by leading a backwards ocho on your side step.) But personally I don't like to think in terms of "resolving" as I feel it creates unnecessary pauses in thought and dance.     

I just want to know if anyone knows any brain washing techniques to rid me of this?
