best windshield for mph

[dirtmodified32]

i thought i read some where on here that the medium windshield was the best for top mph. i looked in the faq and search and can not find this anywhere. does any body know the answer?
because i feel a ton of wind hitting my chest at 80 plus.

i like the medium windshield it works well gets the wind up over your helmet

I've got a tall windshield and the wind still hits me in the helmet.
