I've become pretty comfortable with basic tuning and waxing techniques, but need some expert assistance to answer some finer details on "why" to make some selections. I'm using the Swix wax series but am looking for answers on technology of wax and am not married to the brand.
I’m comfortable with choosing wax based on temperature, doesn’t seem like brain surgery. But I’m not completely sure why I would use CH vs LF vs HF. The difference in price is clear and I understand that the more F your wax has the better it repels water, but that leads to lots of questions.
Seems like CH makes sense for training based on price. But when it comes to racing, why would I use one over the other? Is the difference between CH and LF/HF just humidity hence water repulsion? If that were the case why would the temperature be as important? I would think most mountain venues would be relatively dry and if you’re below 25F there isn’t going to be much unfrozen water in the snow so why would they even make HF5 or HF6 for that matter? Are LF and HF just for higher temps where the snow is very moist? Again that contradicts the temp ratings; I’m very confused by this.
If I don’t have the perfect wax for the day should I focus more on humidity or temperature. So, if it’s 25 degrees out but humid, am I better with HF8 which is too warm but will repel the water, or am I better with LF7 which is in the temperature zone but might not repel the water as well?
Regarding durability, I usually wax my skis every 3 days or so when I’m using CH. How is the durability of LF and HF compared to CH? Are LF and HF going to be "faster" right after application or will it hold up for days at the same performance level? How about the durability of the FC powder compared to CH? I'm told if I cork in the FC powder I’m only going to get one or two GS runs out of it. But I’m going to be ironing it on. How many runs can I realistically do and still gain its benefits? I know it's best to wax your skis the night before the race and not ski on them until you're at the start of the course, but that is just not practical for many situations hence my questions.
That's about a third of my questions but don't want to overload the thread. I'd appreciate any insight anyone can provide.
