During the last cold spell several weeks ago (before SES) I had the opportunity to test the HRRW on two different boards. The temperature varied from -4F at the bottom to an estimated -10F at the top of Loveland Basin (10,800 to 12,000 feet elevation). Both boards were prepared the same, a warm rub on with a wax wizzard rub in. The first board tested was a prototype Donek 183 with the new super glide base, which is designed to reduce static build up. This board ran very well on the groomed snow at these temperatures. There was some sticking on the soft wind blown snow. The second board tested was my F2 Speedster 186. This board was slightly slower on the groomed snow, and did not want to break loose on the soft wind blown snow at all.
To summarize, HRRW works in cold temps to about -10F and the super glide base is noticably faster in these condtions.
Thanks Tony for the chance to test these products. Keep up the good work.
