Phiokka, in Italy:
The PH-1 bindings are great for freecarving. They are similar in feel to the Bombers, but maybe a little softer. The 6mm bail option is recommended over the 5mm bails. It requires 3 hex wrenches for full adjustment: 3mm, 4mm, and 5mm. It is 3D and 4x4 compatible, and the footprint is 14.0 cm in diameter.
The PH-69 and PH-46-6 have a lower profile, and are preferred by racers.
The discontinued Highlander bindings are preferred by racers. These bindings have a low profile, keeping your boots close to the board for high responsiveness. It has an F2-style center disk with a gasket that provides vibration dampening. All adjustments can be made with a #3 Phillips screwdriver. It has a smaller 10.5 cm diameter footprint that preserves the flex pattern of the board. Prior to '06, the toe and heel pieces extended over the board with a very small amount of clearance, causing the binding to rub against the topsheet of the board when the board flexed. For '06, the bindings should have more clearance. Also starting with '06, the bails are now 6mm.
The discontinued Macho has been re-introduced for '06. It is similar to the highlander, but has 5mm bails, and a much harder gasket on the bottom, which provides a more direct connection between the rider and the terrain. It is also one of the lowest-profile bindings available.
Several manufacturers have borrowed heavily from OEM factories: Pogo, Volkl, Hot, Virus
