Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) door mirrors, round better than square?

My new 4/4 has square shaped mirrors on the doors that i find wont adjust on the passenger side to give a clear view of the rear wing for parking.

No matter how i set it the view is poor. Do the round type , Like the librands ones, offer a better view? Are they a worthwhile addition?

Cheers
