I've done it. On an old Nitro R2, pin 1.5 inches right (ie, away from track) of thumb, cg stacked above (ie, straight over from grip center). Acted like most negative weighted balls I've thrown. Very clean thru the mids; while I could use it and play the ditch, it was best suited for when I wanted to play deep and tight, i.e. left of 15 without much swing.
