i would rather never have a head wind, always no wind or a tail wind. i have never encountered a case where i was glad there was a head wind. in my experience rarely is the head wind direct toward me, it is always moving toward with a left right bias. same with the tail wind. so even if i am going as fast as a tail wind only occasionally is there a net zero effect. more often than not there is some lateral component to the wind either due to the wind or the road i am on.
