Today was a fun day. It was only 19f overnight which is far warmer than it had been. Not too surprisingly though, although we could tell the snow was warmer, HF Blue/Red mix was our test HF wax, JetStream Blue wax our best JetStream, and covering JetStream Blue with HelX Red was the best. So, that is what we went with. Sometimes you can't rationalize the wax. The Blue was the fastest (especially in the high end speed).
