thanks daniel.
let's say there is no cut-off at all (i can collect a few more slices), is the coregistration going to be as good with the angled acquisition as the AC-PC? just to be clear, i've posted the AC-PC and -30 angle images here (same subject):

it might help if you look the axial slice to see the difference. the top row is the -30 angle.
