2.75 oz of TOP WEIGHT is fine. That ball is by no means a BLEM or a "lemon". The 2 inch pin is fine as well. Most any driller should be able to give you the desired reaction you want with that ball.
The Phenom Unleashed is a strong ball, but for me, it is just a step down from an oil ball. It wants to get a little TOO long before it tries to turn the corner in oil. For oil, the Phenom would have been the much better choice.
With that being said, I have alot of ball speed (on the KATS, I was 22mph, which on house computers usually would register around 25-26mph). So for someone with less speed this ball could be an oiler.
Goodluck
