Running the ZG Corsa, used the Double Bubble for a while too. The 2 screens are near identical in height at the center, the Corsa is shaped more like the OEM screen. The Double Bubble has slightly less wind protection because of it's shape. Not aware of a screen that is higher but if ZG decided to make one for the H2, I'd be interested.
I posted this a while back, showing the 2 screens compared to one another/one on top of the other, on & off the bike:
