I'd also recommend something stronger, for more oil. The Punisher is god for light conditions, an Reactive Power Groove would be for similar conditions, just a bit weaker.
For more oil, a Nemesis should be a good job. Versatile ball, and you can get it polished or snad it to 1.500 grit if it is too grippy for your local conditions. Another option could be a Black Sparkle Partcile Power Groove. This one handles long oil very well, also a good beginners's ball and good performance for the bucks.
Maybe you find, as an alternative to the Nemesis, a Monster Bruiser in close-out? Has the same PK 18 coverstock, but a lower RG and is polished.
If you are unsure, ask your pro-shop of trust and get some professional advice.
