The 1348 will give you even more height. Either will work as described.
The 1348 fully extends to almost 66" at the base plate with no center column, taller including the ballhead.
I'm 5' 11". The tripod/ballhead/EOS 1D2 combination at full extension puts the viewfinder uncomfortably above my eye level.
Any rigidity problems with all four leg sections extended? I have heard some complaints about this with the 1348.
Don't mean to sound like a twerp--I just don't have local access to one of these to try it out.
Thanks a lot.
