12,
Listen, I feel for you. I've bought several balls that I thought were going to be awesome heavy oil balls, and they haven't quite lived up to my expectations. I've tried 2 out of the 3 in the line, and after what I've seen from the first 2 in the series (which I've drilled 2 of the first one), not going to gamble on the third one. They, too, are ok when they're broken down, but compared to my other equipment, where I can go more left to right with them, these I can't. They don't jump off the spot, and personally, need a surface change out of the box.
Now, bowling on Shark this weekend, and for sure am bringing them. Going to try them on the fresh, and if I don't like the look, I'm probably going to get rid of them. But I know what works for me, and what doesn't. Maybe this weightblock just doesn't roll well for you. Some people work well with certain weightblocks and designs. The balls you listed are all meant to be angular by design, so if you put the same layout on a ball that isn't meant to be angular (Reax isn't meant to be angular, IMO), you're not going to see the same motion. In fact, it may be overflaring and just puking on the fresh, and then once there's friction, it can look different on medium.
Personally, I'm with Phil. I wouldn't drill this ball with anything closer to my pap than 5 inches, and that's even stretching it. If you can't get anybody any information on your game or how the ball is laid out, we're grasping at straws.
