Central vision cast is a mystery to me. It may be usable for open choked guns on big slow targets, but obviously not the ticket for precision shooting. Good shooting at difficult targets demands that one eye or the other look over the middle of the shotgun at the target. "Central vision" would imply that you could be looking over the gun with either eye, depending on which one is dominant at a given time. To me, this means I would either be almost missing on the right side of the target or almost missing on the left side of the target. With tighter chokes, I may be missing on the right or the left.
