There is nothing wrong with the Iron Cross in general. It contains the one esential element for completely blocking the the table and forcing it to pay out. That being the field bet. Plus two more bet positions that your missing. In this year 2011 a Mrjohnrstevens put out what may be considered the ulimate in Craps strategy. He calls it the Craps Blast. The initial workings of this can be found at Best Winning Craps System #1 on YouTube.com. I myself have put this technique to use with surprising and most profitable results. Layered into it's strategy is the Iron Cross. Good Luck!
