I’m chiming in late but will give you my perspective on my experience with my Gen 2 SDR and the puig windscreen.
I had high expectations as Puig put out the wind tunnel simulation specific to my bike (like the one for the 2020 posted) arguably marketing hype but they have at least done some diligence. I wasn’t crazy about the looks but it did make a difference with the wind blast on my chest however it did introduce some turbulence under my helmet (noise not movement). I rode with it for a while then removed it for a few days - the airflow to the helmet was cleaner but I had to make a 1 hour high speed run back home and that convinced me to put it back on as it makes a huge difference at speed to soften the blast on the chest (for me anyway). The other nice improvement I noticed was when I swapped the OEM mirrors for the CRG ones from Rottweiler- it reduced the turbulence under the helmet.
Just like the Covid Vaccine, Everyone’s experience/perspective will be different however just start trying what you feel will best meet your requirements- tweak it as you go.
some pics of my set up - not the best looking but function trumps aesthetics for me.....the added benefit I’ve noticed that I seem invisibile to the local constabulary with this ugly windscreen (and luggage). I should have been pulled over many times for the completely non compliant NRC rear plate mount + Speeding.
