hi all, i have a little case of G.A.S. actually, a big one... A good friend of mine recently won an arca swiss 4x5 and 2 or 3 lenses off the bay(i bid against him on fleabay accidentally, =). oops) Well, he and i went out shooting this morning in our local angeles forest. I had another friends Toyo monorail, and he had his new Arca. I want one. His had the collapsible rail, and with the addition of bag bellows. I must say i had much envy in me at the time. Now the Toyo is nice, but NOT a traveling-by-foot camera; at least not for long distances IMO. Have any of you guys had much experience with using an Arca in the field? I would be looking at getting the 4x5 F-Line, and most likely use a roll film back for 6x12 as well. Also, what about the Master Technika's? How do they compare to say a Technika IV or V? Some help would be appreciated, I'm considering selling the Hassy H2 to get one of my own, used of course.... Thanks!
