if you are racing, or skiing on very wet or icy snow, then use the flouro. But if you are skiing on dry snow (rocky mountains, cali,) then the flouro will only slow you down. Purl uses a monocrystaline mix with only one hardner to ensure the maximum amount of wax to soak into the pores of your skis.
The non-flouro waxes come in temp specific and all temp. The all temp ranges from the middle of the cold range, to the middle of the warm range. It is simply called all temp for easier identification, but should be called average temp, because the average ski day's snow will fall into this temperature.
oh, did i mention that a brick of this stuff will last the entire season! I wax my skis every other friday, and as needed between thos fridays. Needless to say I wax my skis a lot and the brick of Purl wax that I used last season is still going strong in my garage. I used about half of the brick for upwards of 25 waxings. Because the wax is all of $5 a brick it wont kill your bank to get the new $20 all waxes deal.
For $20 you can get some Swix All Temp Soft wax that will last about 20 waxings. You can also get One brick of xtreme cold, one brick of cold, one brick of the average/all temp, and one brick of the warm wax, along with some stickers from Purl! With an average of around 40 waxes per brick, that supply will allow you to wax your skis upwards of 160 times! Plus it doesnt expire like some expensive race waxes do, so when you dont use the entire brick one season, it is good to go for the next year!
no im not a rep, yes i do ride for them, but this is a testimony of facts I tried to include a minimal amount of opinion here.
