sorry for the cross post, but it seems that the macro discussion section was the inappropriate section for this question:
Hi all.
unfortunately I live in a desert.
and therefore do not have a truly available "B&H" for some help...
I am looking at tripods (for the future) for general use, but with a specific eye to macro shots.
I kind of liked the idea of the mobile middle column of the manfrotto 190 xprob, but it doesn't seem available in my area.
and on manfrotto's site I didn't see a notation as to which of their other tripods had this feature.
In general, i plan to mount the 7d with the 100 macro and up to two flashes with modifiers....
and I had planned to get this on the xprob190 and 498rc2...(which is a bit of "overkill" but I have (future) plans of lenses like the 150/180 macro and maybe even a 70-200 f2.8.....
so my question is this:
any other ideas about good tripods for the macro scene? does the mobile middle column really help in macro shooting, or is it just my own misunderstanding?
caveat - the lighter the better! 
:
/5 bits of glass/dual triple tubes/Sig TCs,
) but I will be considering 1-2 sets of kenkos plus 100 macro plus/minus reversed 50mm on the end with and without the focus rail. I am a bit worried about the torque on the ball head. great idea on the superclamps. I will look into those. Thanks a lot.
