Which wax to use

TheGhostlySheepSo I'm going to les deux alpes in france in a week. I need to wax my skis before the trip but I'm not really sure what wax to use. I've had a look at the weather forecast and currently the temps are very cold (between -10 and -20 (Celsius)). It's supposed to warm up when I'm out but the temperature varies quite a bit between the base and higher up the mountain, seems to be generally betweem 0 and -15 during the day.

I have 2 waxes available to me. One rated at 15 to -8 and one -10 to -30 and I'm not sure which one to use. The other option is for me to order a universal all temp wax such as this one I found on amazon: https://www.amazon.co.uk/Datawax-DataWax-Universal-Ski-Wax/dp/B00AKYRUMW/ref=sr_1_5?keywords=ski+wax&qid=1638473577&sr=8-5.

However, I've heard that all temperature waxes aren't great for powder/ anything that isn't groomed. I've also heard that it's better to use a wax for cold weather in warmer weather than it is to use a wax for warmer weather in cold weather?

I have no idea how much truth there is to either of those claims hence why I'm asking here.

Which wax should I go for?
What happens if I use the -10 to -30 wax in warmer weather?
What happens if I use the 15 to -8 wax in colder weather?

mrk127See mods banning @dolanslebensraum is already negatively impacting the community, he can't enlighten us with his wax and base knowledge.

Anyways, you're right about generally wanting to error on the side of using a colder (harder) wax. But also you want to use a harder wax in more abrasive snow, think fresh pow, man-made snow, dirty snow, ect. All temp wax is usually fairly hard so I gotta say your claim about all temp being bad for pow and off piste is false. If you are looking for a new bar of universal wax I think this stuff is bomb https://the-raceplace.com/collections/beast-ski-wax/products/beast-1-everyday-glide-wax It's somewhat thermo-reactive. The stuff you linked looks ok for a cheap low-fluoro wax but fluoro wax really isn't necessary unless its really wet and humid conditions imo. @dolanslebensraum would disagree with me about the fluoros.

Session@DominatorJacques would likely be the best source of any waxing info on this site.
