Bogen 3021 with leg wraps and either an arca ball head or a wimberley, when useing my large lenses, I also have a 3047 QR for it, that gets used with the 6x6 gear,holds well and is sturdy, have used for medium and large format work, I also have two of the old very large Tiltall tripods which are rock solid and quite reasonably priced on the used market, I have one with the orginal 3 way head and have modified one to accept aftermarket heads., but I would have to say my 3021 gets the most amount of use.
