I had this same question and he told me that they are really only 1" difference. He went with the longer ones to get the mirror further towards the center when they are folded down and that they offer a little more adjustment to see past your shoulders when they are up. That is what I just ordered. I'll report back after I have tried them out. I am really looking forward to these.
