It is smart that you are out here asking for opinions. There is a flood of new board types out there in the last 2 years and it is hard to get a solid idea of what is working and what was rushed to market. When Mervin re-initated Rocker a few years ago, and it caught on, everyone had to introduce their own "new thing" ready or not. Business is funny like that.
Do you remember when a flat board meant it was time to pull of the bindings and nail it to your wall? Well, what has changed? Manufacturers will telll you that these boards feel stable and "broken in", but do some web searches, real
users are widely reporting that they just feel broken down.
There is something you should be aware of with all kinked rocker, partial rocker and half and half rocker boards (there are actually to many variations to list here). These are all designed with various stages (you can call them kinks) to the structure of the board. The idea is that these will better line up with the rider's binding mount positions and when weighted will better form the end curve (or arc) of the board.
BUT, there are a lot of things that keep that from happening. First off, all riders have there own weight, stance width, angles an even style, and all of these thing can fight where these pre-determined kinks or bends have been placed on the board. That is why the industry is seeing such a huge turnover of the original kinked and rockered boards. They all have "grab spots" that tend to act in odd an unexpected ways for different riders with different mounts and styles. Now if you add "wavy" edges to that...
If you are expecting a smooth ride, these are not for you.
As with all designs, there are some very good things about these boards, but they are VERY specific, and should not be sold as all mountain boards.
