Both sit low so an 8" might be too low for what you need.

Note that with the LRS as long as you don't take the plastic wrap off you can return or exchange it.

Check out youtube for the LRS measurement.
Note that in the video it states the windshield should be between your top lip and the nose.

I have mine right at my nose.
This allows for higher air flow stream which reduces buffering for my Wife.
