Croissant expedition - part III

After years of gawking at some croissant-centric blogs (*ahem* txfarmer's and weekendbakery), I decided to conquer, once and for all, my biggest fear in all of baking. I've been using weekend bakery's recipe, and for the most part, it has been great. 1st attempt was a success, 2nd was a disaster, and 3rd was pretty good again. My biggest problem, however, is trying to get consistent and even honeycomb structure with each croissant. Seems like I would only get 2-3 perfect croissant per batch. Any tips/pointers would be greatly appreciated!
