Nose: OOB, I found the Dynamo to need good head/mid oil to keep from burning up. That's why I had my best initial success on fresh first shift THS, or Sport/PBA patterns. I didn't want to be limited in it's use, so over time I've had it everywhere from 800-4000 grit, with and without polish. I've found the cover reacts well to different surface changes and corresponding oil match-ups.
Do all balls have this level of versatility?? In my experience, no. Generally, I can't take a high-RG pearl piece and turn it into an effective oiler. I've tried with a few balls, most recently my Ebonite Singer low-flare (I was bored), and it just didn't work. Conversely I've tried a few times to dumb down the reaction on my Super Carbide Bomb, and it tends to kill all reaction. I now keep it at a 35 micron Trizact finish, and I have the big hook reaction back to where it will stay.
Some balls react well to wide ranging surface change; others don't. Again, I found that the Dynamo does.
I don't know that the Dynamo was 'different' from every other ball on the market. I don't have the money or time to drill up and test every new ball that's released. But it was one of Lane#1's better pieces in recent years.
