If you're new, you probably want a surf style board. That's where a lot of people start out. They are generally a little more stable and are good for carving around, having a good time on the wake and maybe getting some airs.
Skim styles tend to be a lot looser and are made to be able to do spins easier, but they are generally not as stable or straight tracking as a surf style is. This is due to how they track through the water and their much smaller fin setups.
Most people prefer to have not just one board, but a variety of boards, maybe even just one skim, one surf, or a few of each. Each board is going to have different characteristics from another board, even as little as being a model year different.
Definitely let us know height, weight, and what kind of setup your boat is running. If you have a killer wake, you have a wider variety of boards you can run. If it's not so great, you will want something a little bigger, and definitely one that tracks faster.
