Norma,
you're right, the pics you posted show much larger rims and better looking pies to me. the dough looks similar though, maybe not quite as much gas. i'm not sure about overfermenting causing lower springs. it's certainly happened to me but i can't really recall that part of the result. i bet someone here will have an educated opinion on that.
your photos are great, thanks for pointing me back to your thread. i remember when you posted that but i haven't seen a good shot of NY pizza since i've made an attempt or two at it myself. i have another post soon about my visit to Patsy's on our way back through the City on Wednesday. needless to say, both were eye-openers for me...
