I'm 5'11", ergos aren't hugely different from stock, maybe just a little more uncomfortable over long distances without the risers, although I have done a 6 hour 400 mile ride with the Driven bar and no riser and my back only started to complain towards the end of it. Tough to really say how the wind compares to stock, but I will say the Driven bar on it's own certainly seems to put you in a better position to deal with the wind than with the Rox risers. I always have a Puig screen on when I use the risers and it seems to be no less windy than the Driven bar on it's own with no screen. The Rox risers I have are the 1R-P2PPK model.
Looks like the Street Low might be slightly lower than the SBK. Rolled back to zero, just enough comfortable clearance not to squish or graze the thumbs with thick winter gloves.
Not exactly the same angles, but a general sense.
