Forecast/Conditions: some snow accumulation is expected on Saturday. Saturday evening low -5F, racetime temps expected to be 0F to 2F. Sunny and calm. Course will be partly on manmade loops and partly on natural snow.
Base: LF10 or MF10 Green, scraped while bases still warm.
Glide: HF10 Green, scraped while bases still warm. Brush with fine steel or copper brush, then horsehair, then hard nylon brush. Make sure to rebrush skis after testing them for a couple of KMs.
Top: HF10 Green will possibly be fast enough on it's own, but SFR92/HF13 block will be worth a try. Iron the first crayoned layer through a sheet of fiberlene, then roto- or hand-cork a 2nd layer, then brush.
