That's really helpful, thanks! So, if I'm understanding correctly: the mtl 9251 does only extend 'normally'. Would you know if it allows you to put the center column upside down though?
Yes, the mtl 9251 does allow you to put the center column upside down.
How did you like the 9251 the time you had it? How was the build, quality, locking system? I just checked youtube where there's a vid for both the 9251b and 9351b.
I never took a picture with it. I just pulled it out of the box and fooled around with it for about 20 minutes. I thought it was all good, except I wanted the lateral arm.
The 9351b DOES have a lateral arm, a feature I think I would really like (no experience with this whatsoever). If anyone can give me some information about the lateral arm, that'd be great. Like, how does it function, what are the best uses for it, and how sturdy are the locks.
The lateral arm is really useful whenever you want to look down on things.. very often used for macro work.
Here is an example of a shot that I took, that made me realize that I wanted the lateral arm (I plan to retake this soon). Because I had to balance the rings on the bible, I could not simply change the angle of the bible to get the look I wanted; the bible had to lay flat on the table or the ring would not stand up. So I could not get the camera more above the bible without the arm (I suppose I could have if I had put the bible on the floor, but I was working on a table).

On the Giottos, to use the arm, you simple remove the center column, then there is a flip-up collar (for lack of a better term) that you lock in place, then slide the center column through that horizontally or at an angle. The flip-up collar is actually the top portion of the tripod where the center column slides through (when it is in the normal vertical position) anyway. It is a pretty slick design.
