You have to remember, the IQ Tours are all low RG balls, so the core wants to start revving a little early anyway. When you add a 3 3/8ths pin that's going to make it rev up even earlier, then a P3 hole which gets the ball revving up even more. What's going to be left for the last 15 feet?
The 3 3/8ths pin placement with the P3 hole is getting the core to spin up and kill before it even hits the breakpoint. What you did there was use the two strongest elements in drilling to negate the backend of a ball that naturally wants to go long and make a big move down lane. I would either plug/redrill, sell it for a nice dollar and purchase a new one, plug the weighthole and maybe add a "Motion Hole" if you can get the statics legal, or put a little surface on it and use the ball when you have to go more direct and up the lane. That layout that you have in it now will NOT be something you can stand left throw right and get it to jump off the spot.
