I think what John said in post #2 is the best advice. To me, a fresnel is wonderful for composing, but I find that it is harder to focus critically, even the Maxwell that came in my 8x10. And the coarser the GG is, the easier it is to focus but the harder it is to compose because of the "hot spot". The plastic "glass" I had in my Wehman popped into focus like nothing else, but it was just too dim for me. So it's a balancing act that may not have the same solution for everyone.
I was chatting with Don Dudenbostel, who has been a commercial and fine art photographer since the 1960s, and he said he never knew of a professional that used a fresnel in a large format camera.
