For almost 3 years now, I've been using a Manfrotto BeFree as my main tripod for both photography and video. It's light and compact, and stable enough even for my Bronica SQ-Ai.
My recent road trip to South Dakota seems to have taken a toll on the Manfrotto though. One of the sections was already loose, but the mud and snow in the Badlands broke it for real, and also made me lose the three "feet" (if that's the correct name) on all three legs.
After looking at tripods for a few days, I decided to go with Manfrotto again and get the heavier, but also taller Manfrotto 055XPRO3 (what a name) with a sturdier ball head, too (I was having some problems with the old one when using long lenses).
I'll have it in my hands this week, and I'll be reporting on how it feels very soon.
