You can hardly go wrong with swix. They have been doing it longer than anyone and have it dialed. If you are getting nitty gritty temperature specific, Swix is the way to go.
I've been using Bluebird cold weather wax this year and last. Fairly impressed with it. I forget if I have any Bluebird warm weather wax. I am thinking not. I know I've got some One Ball Jay warm weather stuff sitting around. Thing is, in my experience, warm weather waxes are generally about the same. It's the colder stuff where the manufacturer really shines through on who performs in those temps. I could be wrong though, as I spend more time in cold temps than I do in warms ones each season.
