There is some new rules coming banning HF at the u14 and below level
Not sure about LF
Probably will not ever hit FIS level
With ski md pro glide system you don’t iron wax so you use way less wax so using LF for everyday training is not a big deal
My son is using LF mostly except for red and yellow temps
No flouro powders
He does use turbo overlay for SG
Usually I buy Vola over Swix as it’s much lower cost and I feel it’s easier to work with
We mask up and use a respirator when aerosolizing the wax and ventilate well
You have to wash your hand like 5 times after you even touch HF as it is designed to Shed water
SL skis you can race with CH wax means nothing, GS is LF, SG is Wax critical and use overlays
if You French Fry when you should Pizza you are going to have a bad time
