I', 6'3 and had this issue, changed the standard screen for a DB one and all it did was move the wind flow from hitting my chest/neck to right in the middle of my lid, stuck with it though as I can slouch lower and into the dead air better :-) I have seen the air deflectors that go on top of the screen, an adjustable blade that you can move to suit your own height etc but at £100 a go......
