Will the decision for either 1 straight or 3 straight or left and right turn be once you choose and put template down you have to commit to it or will you be able to change if you don't like?

I'd imagine it would be like any other time you have to declare something. You declare your intent, then follow through whether you have second thoughts or not.

You can expect a FAQ stating in competitive play you must declare both template and direction you plan on placing the bomb before you drop it.

Sort of funny that they FAQed the 1 bomb per turn for the Adrastia title and not Emon's pilot ability. I guess it still keeps Emon from dropping a 15 point cluster proton bomb.
