I use Feisol carbon fiber legs, and a Manfrotto 3038 ball head for my Pentax 67 system that includes lenses up to 300 mm. I also use it for my 4x5 kit that includes a rather large 450mm lens. The weight and mass of the ball head absolutely damp the sometimes considerable mirror/shutter slap of the P67, and the thing is rock steady on the Feisol 3301 legs. The head (used) and legs (new) come to about $325 and I feel no need for anything more expensive. Yes, the head isn't light, but again, that mass is a large part of the whole point of using the tripod in the first place. Here's a link for the Feisol legs. Kerry Thalman also carries a number of ball head lines that are worth checking out.
