I drilled three different Reigns, two pin over, and one pin under. The pin over Reigns work great. They read the lanes the way they are supposed to. The pin under, not so much. For me, the drilling fights the intent of the ball. The Reign and the Fast share the same cover. I have a pin under Fast that works really good, but the core is alot weaker, and it doesn't use up too much energy early. This goes back to a post I made in a different thread, about matching the drilling to the strength of the intent of design of the bowling ball. Using a pin under drilling isn't really allowing the Reign to perform at it's optimum design intent, long and strong. I AM NOT SAYING to never drill pearl balls pin under, I have a pin under 2nd Dime, and a pin under Gravity that are my 2 favorite balls, but I am just saying that you are going to risk a possible miss match of cover, core, and design intent.
