Wind Buffing on GT

I use a powerbronze screen its not an extra large touring screen and cost about £100 ish, then I added a 4 inch add on screen from amazon only cost about £20. I was a nightmare with the original screen but its great now no dirty air or noise, im 5ft 10. I can see over the screen which is how I like it. Cheers.
 
Never had a screen on any of my bikes, just whatever they came with and always down as far as they could go. Don't like the disturbed wind behind them and have done a lot of long rides with no problem. Just completed another 15k around Oz with the basic fly screen on the old R111.
