I've been quite happy with the Bogen 3218. I usually use a 3262 medium ball head on it, and that's fine for the Sigma 400/5.6 with ZX-5 or MZ-S, with their attendant battery pack. It's small and light enough to carry around all day, and heavy and sturdy enough to make a good blunt weapon when you're out in the woods and the local fauna strolls up. :-)
