I switched to the lower heeled 1/2 inch Rogues in August, from the 3/4 inch Do-Wins I'd been using since 2008 or 2009. I generally like the 1/2 inch better for doing things the way we do them here, especially pulling.
The lower heel would result in more forward lean in the squat, not less. The higher heel allows your knees to track further forward, necessitating less forward lean if the bar is to be maintained over mid-foot (which, of course, it must). The extreme example of this is a front squat, where the knees are way out forward and the torso is basically vertical. We purposely don't want this anatomical arrangement in the squat, for all the reasons detailed in the book and repeated at the seminar and in many threads here on the forum. But the difference between a 1/2 inch and 3/4 inch shoe in this regard is not significant for most trainees.
I like the 1/2 inch, but either one is a fine choice.
