I've got a gloss PP screen, works great solo, but put the top box on or a pillion and the air flow changes, and becomes uncomfortable. So I use the PP one most of the. Time, and standard one for two up. I would go with the matt one on your bike.
I don't mind at all the look of the stock one! I like the big size and shape of it, together with the engine lugs, spotlight and barkbusters the bike looks more majestic, like a proper adventure maxi enduro if that makes sense! It might sound strange, I know, but I kinda enjoy making it look heavier and bulkier... I just need to open up the throttle to tell the shocking truth
