I'm buying a new tripod that has twist lock legs. Previously I've always had tripods with lever lock legs, like the Bogen 3221. I'm looking at two very similar tripods, one with 3 section legs and the other with 4 section legs. I really like that the tripod with 4 leg sections folds into a more compact length. What I'm not sure of is how much of a bother it will be dealing with the extra leg section as far as time required to set up and take down. There are a lot of tradeoffs with tripods. Is the extra leg section something to put weight on, or a non issue? Thanks!
