I have that exact model, but it has 4-section legs. I really like how compact and light-weight it is. Plus, the look rally cool and I've have multiple people come up to me asking about it (since it's rare to see one).
I have had no problems whatsoever with it, except that I wish I bought a heavier-duty RRS ball head because of my 1D X. That being said, PM me if you're interested in a slightly used 3LT.
