I just did a modified version, 5 1/2" pin-pap about 1/2 under my bridge with MB at 45*. I have only thrown a few balls with it so I cant really give you a review. It was on a pattern with fresh backends, ball got through the heads clean and made a big back end move. This was a box finish. Hit me up in a week or so after I have had a chance to really use it.
