We decided to push the envelope a bit further this season with a new board that is longer and wider than the Spruce 120 but still retains the 7.5 meter turn radius of a true skiboard. Testing of the board over the summer by Dave Stevens and Jack Jue of the Spruce Pro Staff, confirmed that it is a very powerful board that provides a new level of stability and speed without giving up the fast turn initiation of a true skiboard. The board is 130cm in length and has a width profile of 160/112/145. The flex is a bit stiffer than the Spruce 120's, but it is still a relatively soft flex board and is well suited to larger riders and to deep powder. The picture is of a prototype board with a paper topsheet and Pro Prime riser/binding. The Sherpa will be available in January '08 from skiboardsonline.com or directly from us.
