i went with a GAHH top and love it. i like the slight change in the profile and shape of the car that it brings as well as the more "aggressive" look. of course no longer dealing with the plastic is reward enough.
as for the lowered visibility behind you, it's something you get used to quickly. you can still see behind you, but you no longer see into the cabs of pickup trucks. that's about it.
