Crepes of Wrath (revisited)

Hi Floyd, 

I know the original post was quiet a while ago, but I just ran across your crepe recipe and I was curious...  The Hensperger recipe calls for 2/3 cup water or light beer.  I'm not much of a beer person (the one exception being an occasional inclusion in pizza dough) but I'm wondering if the carbonation makes a difference?  Do you think sparkling water might be a good compromise between the water and beer?
