Thanks for the suggestions, gang! I will say, I had not considered the venom shock, though I always see it strongly supported by those who have thrown it. I will confess myself really into the IQ, as I had a great time with the Fusion when that ball was around. I will look around a bit more, but given my ball speed, I would think that surface changes would definitely be in play on a number of balls in the running. Most likely, getting them to 4000 grit, as it helps, and I really never keep a ball with less than 3000 without modifying it, due to my type of roll and "marshmallow" ball speed, lol.
