I love how much I can see in my f150 mirrors... they are really big and give a wide view of what is happening around. When I drive I like to be aware of my surroundings and I cannot drive without mirrors. When I first got the round mirrors for my rocket, I love the details on them, love the design but initially I felt that I lose some rear vision. After a few rides, and adjusting them to my taste, they are just fine. I can see what I need, car to my right, car to my left. I think the loss is a bit on the blind spot area but then again, I always check that before changing lines turning my head, so no issue there. A larger mirror can give you more of that or even real state to add a wide angle mirror, but, I don't feel it's needed. And I am someone that needs my mirrors.
