Did this with a lightly polished Impulse zone. Pin under ring, p.s.a. at 90 degrees with an x-hole on the v.a.l.
Ball works great on fresh and really wet/dry's. Likes to have you put a lot of hand in it without it going nuts. Very consistent reaction. I would do it again.
P.S. As a matter of fact, I've been thinking a classic zone set up this way might be good and was thinking about trying that.
