Forecast/Conditions: Chance of snow Friday night and Saturday am. Friday night low of 4F, race time temps around 10F, winds 5-10mph. 60% chance of snow race morning, several inches expected.
Base: LF10 Green, scraped while still warm, then brushed
Glide: HF10 Green, scraped while still warm. Brush with fine steel or copper brush, then horsehair, finishing with hard nylon.
Top: SFR92/HF13 could help, but with new snow and wind, it could also be slower than the paraffins. Test a roto-corked layer of SFR92/HF13 on a test ski compared to the HF10, and you should be able to tell a difference.
