You can order any of these blades from tabletennis11 and request a light blade. They will hook you up with a light one. Just received a light (83g) Nittaku Acoustic from them, while my old Nittaku Acoustic that i already have weights 86g.
The Yasaka Sweden Extra is a nice and very affordable (40$) blade than can help you develop your strokes. If you wanna pay 100 bucks more, you can go for the Nittaku Violin (140$) which is even more nice in feeling and controllability.
You should also think about downgrading rubbers, tbh.
