I asked a similar question of my (very experienced) tail-dragger instructor a couple of years ago, in a PA18. Whilst taxying along with a tail-wind (I think it was about 15kt), he suggested I stick my hand out of the window. As soon as I felt the relative airflow on my hand it was obvious that the combination of forward movement of the aircraft and the propwash resulted in the relative wind coming from in front of the aircraft, therefore the stick was held back in this case.
