Clearview is the way to go on the Touring, but it's different with the Roadsters. I have a 19 inch Clearview with a recurve and it's perfect - almost all the turbulence goes over the helmet. The stock shield is turbulence hell. The Wind-west looks awesome, but I think it would have to be a tall version if one wants to avoid having one's head batted around like a ping-pong ball at speed.
It seems to max out at 16 inches and be quite a bit more narrow than my Clearview, so I would presume it would be fairly turbulent.
