What is your height? I tink it plays an important part in choosing a tripod. I am 1.8m tall, when i use a Manfrotto 190pro, i have to bend down . This hurts the spine in the long run. Hence, i bought 055pro instead. However, the tripod is bigger and heavier than 190pro. Well, the weight and bulk is no concern to me. Most important, the tripods helps taking a good picture.
165-167 depends...i cant remember when i last measured my height.
weight isnt too much of a factor...of course..i dont want a lead tripod...neither a CF tripod (too exotic)
