If a calm bubble of no bufferting and open visor riding is what your after then the givi or the Puig touring screen will work a treat. Be warned though, the bubble causes 1 major issue in my opinion and that's fogging of the visor in wet weather due to the lack of any airflow through the front if your helmet. Assuming we all use pinlock visors which are great, they still need air flow to help them work. Ride in the bubble in the rain and your visor will gradually fog, so naturally you'll open the visor, then water gets in and your left with streaks on the pinlock and a fogged up visor, which is crap.
