I've used several height wind screens on various bikes over the years. All previously were for the sole purpose of reducing arm fatigue, from the wind pressure on my chest. I defer to those with fly screens for an assessment on how much relief that small of a screen actually provides. I'd need a lot of convincing. I now have the taller tourer wind screen but the wind strikes me, force magnified, square on the face shield (5'11"). Perhaps if I had the "summer" screen the max velocity zone would strike at a lower more comfortable zone. I don't look forward to another impact with a dragonfly on my sun glasses. Though I don't care for wasps down my jacket either. But perhaps the strike zone with a fly screen would be square on the tool shed; and, impact would be less felt.
