I have a Watermelon and I can tell you, the added ventilation looks good to me. If it's lighter or a little more sophisticated in the fitting, that would also be nice. I'd like something that adjusts to my head rather than just picking padding thickness.

The graphics are pretty boring though. The colors are subdued and the patterns aren't interesting. I wouldn't have gotten one if not for that watermelon pattern or the other fun options in the original version, and there's nothing about these that appeals to me that much.
