Any time you try a new league/format, it's important to see how the new scoring affects players compared to the normal 5x5. In yours, if it counts losses for pitching, you'd tend to stay away from SPs from poor teams, pushing Oliver Perez, Ben Sheets, etc down your list, since their wins will most likely be offset by their losses.
Run a normal 5x5 on rototimes.com's $ value generator, then run a 6x6 with your league settings, and see which players move up more than 10. Those are the ones you'll probably want to target with the new categories added.
