I thought I was being organized this morning and tuned & waxed skis, w CH5 bc it was supposed to be cold. Just checked forecast and it changed! Now btw 20 and 26 during race time. How exact a science is this? Do I ... need to start over with CH6? Not that I’d necessarily be willing to do that but I’d at least entertain the thought or get my kids to do it themselves ..... Tx for any info
