Thanks for the replies. My wife's family is from the Four Corners area of CO, and we've noticed when hiking there that the 4x5 + holders + tripod begins to weigh one down in the thin air. I wonder if Steve Grimes's shop could adapt a biogon or such to the C220 as an alternative?
Time to hit the weight room, I guess.
In Illinois, where I currently reside, the legs to get closer or farther away works. In Colorado, that's a good way to cause a sudden adjustment in both distance from the object as well as relative vertical positioning.
Ole, a stone is 14lbs (~6kg). I first encountered it in english literature, and then on a physics test (convert the force from question 3 from SI units to Stone Furlongs/Fortnight^2)
