SL/R230: The Windscreen Revisited

I didn't have it on long enough to test it out. Has anyone noticed a difference or not heat wise?
If you raise the rollbar, not only do you have to look through 2 layers of screen, but the wind goes down behind the roll bar and it's worse.
Anyone who doesn't want theirs, I'll buy it for a reasonable sum, my cigar ashes eventually burn little holes in them!
