Just to throw my opinion into the mix, if I were to get another pow board this season after just selling my trusty K2 Gyrator (instead of a possible split purchase) I'd prob be considering stuff like:
Capita Charlie Slasher, Salomon Powder Snake, and Jones Hovercraft for that pricepoint.
I'd have to do more research for the higher pricepoint (more in line with the Gyrator and Ride Slackcountry) but I'd look into stuff like the Salomon Sick Stick, Rome Notch, Nitro Slash, Signal Epic, and Smokin Pinner
