Hey John,
My advice is to try some different balls, starting with some of the WGT balls, as they are less expensive than other brands. Perhaps the G12 S, spin balls, rated at 2.0 meter speed. They start at 64 credits a sleeve. I'm at lvl 84, and still often use the WGT G13 S vapor ball. While I treat them as a practice ball, I've posted some of my best scores with them.
They start at 124 credits per sleeve, and have a meter speed of 2.5. Try to find something that you can adjust to, without spending anymore than necessary, at first. Generally, the slower meter speed you want, the higher the price of the ball. And the higher lvl you have to reach before they unlock.
If you look on the forum, you can find an interactive equipment list posted by Scott Hope. In it you can look at all club and ball specs, narrowing things down to a particular meter speed if you choose.
Feel free to send me a friend request, and I'll get back to you with a PM if you want to talk to me some more privately about this. I can let you know what I've tried, and have success with.
Good luck
