Hertel is great. It limits when cold and like all non fluorocarbon wax it looses effect when snow is warm wet and grabby.
Mix in cold swix ch4 or sub when really cold.
Can't condone fluoro, but there are shops still selling it.
I have a lifetime supply of Hertel.
I wax the family's skis multiple times each season. Hertel makes sense. Use a cheap shop wax for summer. I have some other all Temps and temp specific, but 90% of the time Hertel works great for 4-5 days before waxing is needed.
I need to get a roto brush or two and an evo. Maybe I should paste, but where is the work? In light pow anything goes and most of the wax issues is from too.much groomer skiing. I don't race, so an all temp works just fine for most situations.
Let me reiterate, I love Hertel wax. Was given a cheap travel Iron, cheap edge file guide, a stone, a scaper a cork, and a couple small bars of Hertel wax as a gift when I was 14 from my Dad whose leg getting crushed in SLC at age 22 kept him from skiing. He planted the seed.
Hertel works and for me it has soul.
