Maplus Med Racing Base Solid Wax
Pros: Hard-ish wax that holds up
Cons: Hard-ish wax that takes a bit of work to spread
Prior to attending ESA Aspen Snowmass, I waxed my skis with the Maplus Purple wax (2 coats) and was able to go 4+ days before needing a touch up. The really amazing thing is that Aspen, Snowmass, and Highlands was in need of some fresh snow, yet this wax held up.
It may take a little effort to spread this wax because its fairly hard, but is well worth the effort.
Pros: Durable surprisingly fast in many conditions
Cons: None (but as a harder, higher-melt-point wax, it is expectedly a little more difficult to work with than many "universal" waxes).
Pros: Costs, Performance, Longevity, Easy to work with
Works about as well and lasts about as long as Swix LF4. Cost is less and the wax is easier to work with.
Pros: Less wax used, less scraping.
Because it is so firm, this is a great wax to start doing the "hot touch" technique with, especially for daily waxing.
Pros: Fast, durable and expanded temperature range
Cons: A little harder to apply due to medium/high-melt paraffin
For the last couple years I keep coming back the Maplus Race Base Wax for my primary glide and base waxx. When in doubt on temperature and humidity ranges, this wax performs well beyond it's design temperatures and it loves Colorado snows for most the winter. Since it is a more durable wax it can last up to a week of skiing, which is more than twice the durability of low melt patraffins which are very common. It saves time, effort, protects the bases and I can't recommend it enough. Plus, it's a great base for abrasive spring conditions topped with soft (Hot) LF Universal or P2 Hot (hot butter for your corn) wax for better glide in wetter conditions.
