Curt, the biggest problem you'll have with an 8x10 is wind. We were along the southern coast yesterday, it was absolutely gorgeous and the wind was blowing close to 60mph. I brought a Mamiya 7 on this trip and am glad I did - messing with a 4x5 would have been a lot of work and frustration on some days. I'm sure you can get days when an 8x10 won't blow over, but we didn't have many during this trip. I just wish I'd brought a 65mm for the M7, my usual 80mm was just a little tight at times, and the 43mm is very wide. I hardly used the 150mm and would probably leave it home next trip.
