Stance will be narrower. Think straight down, straight up (i.e. more forward knee travel)). And I bottom out hamstrings on calves, but if you want to stop at parallel the world won't end. In general, the front squat will be the deepest of the three (low bar, high bar, front).
I prefer deep, but I don't think I'm that deep. I'll work on a narrower stance and get some vids for everyone to critique.
