Sorry, I haven't. I did ski the slightly-beefed up ski from the Red (Fischer Cool Heat) and it was very good on the hardpack. Incredible lateral rigidity, but perhaps overly aggressive. I think it could have used a base grind and 1-degree bevel put on the base, even though it was out of the wrapper. If the Red Heat is similiar to the Cool Heat, or even as good as the RX8, it should be just fine on any hard snow you can throw at it.
