It's really going to depend on your personal shape, helmet and ergonomics.
Personally, at 160 cm and 54-ish kg, I've never had a bike with such good wind protection as I have with the R3's stock windscreen. I wonder if it's actually too tall for you, so that you get some buffeting from there being empty space where the engineers expected your shoulders to be.
Maybe you might even try taking the windscreen off entirely and riding it that way for a little bit, if it's better than stock, that would tend to say you need a shorter, not a taller, screen ...
