A quick update, I have now taken possession of my tall screen for my 2014 crossrunner ( I will post pictures soon). My first thoughts are that unlike the original screen, the holes are drilled on the curved face of the screen, (the original is moulded with flat areas around the holes) having fitted the PowerBronze screen I noticed that the top edge does not appear 100% uniformly curved and I can only put this down to different tensions on the screws. I will tinker and get back to you on this point. The screen is a little noisier in use compared to the standard one, due to the fact it pushes the air up to level with my nose rather than hitting me in the upper chest on the standard screen. The upside is that I now no longer have my helmet being bobbed about by the wind at higher speeds. (I'm 6 foot tall with an inside leg of 32").
One other slightly distracting thing is that on unlit roads at night, some of the light from the headlight is diffused and shines through the edges of the screen, giving an H.U.D. type of effect on both sides and the top edge of the screen.
