I know im not that tall being 5'9 and all but the guys that are really tall defending the sunroof etc. Wouldnt you want to raise your seat up off the floor a little to see over the hood to help overall judgment of your car? Personally I raise my seat as high as I can.
Edit: Disreguard that made no sense... Guess your head would already be up high.. der der.. bored at work ; ;
