Wind Deflector For A 2008 Bonneville

Can any of you recommend a good wind deflector for my 2008 Bonneville screen. The screen is the original Triumph part and it creates some turbulence and buffeting. I am 6' and I put the screen on each autumn for use through the winter.

 

Thanks Tal, Have you ever used one of these? If so, how did you find it?

 

I bought the MRA screen tour. Yes, at £100 inc delivery it wasn't cheap.
It came with screen clamp and direct bolt attachments. You assemble it yourself but that was straightforward. It looks a bit ugly but it's only for winter time.
I had hoped it would work in the down position but due to my height and very upright seat position I had to use the more upright one. It seems to be infinitely variable between the two. Yes, it works very well. I have only tried it to 70mph so far on the motorway but it was very stable and vibration was minimal. I can easily see over it.
The buffeting and turbulence have gone.
