I get a bit of wind noise off my standard screen around 70-80 mph, so got a double bubble from Powerbronze thinking it would reduce it.  It made it far worse, I was getting wind noise from 40-50mph.  The standard screen causes the wind to buffet on my chest area but the double bubble screen raised it to my head making it alot noisier.  I put the standard back in and sent the double bubble back.  I wear ear plugs all the time it helps.
