The Eagle Screen Touring (comes with or without lip) looks very similar to the Zero Gravity Sport Touring (ST) screen.
I have a clear ZG ST and it raises the wind-hit-point by several inches - for me (6' 3") at nose height.
The clear (not smoked) version doesn't add much visual height either.
Downside can be some noisy turbulence around the helmet, but that depends on many many other factors...
Some turbulence can be avoided with a pair of PoorDucRiders fairing stays - they take away a lot of buffeting.
As a matter of fact, I suggest trying only the PoorDucRiders first - maybe that's all you need.
