Mine is drilled pin above and to the right of my ring finger (RH), MB is just to the right of my thumb and a small x-hole on my VAL. I guess it could be considered "stacked". I took the polish off and brought the surface to 4000 abralon. As long as I keep my speed up this works great on a used up shot on wood. I have issues on a fresh shot, but thats more of a mental issue, lol.
