I'm looking for a recommendation on a new carbon fiber or basalt Gitzo tripod. I have an older 4 series Gitzo aluminum that I will be replacing for use with a new Canham 8x10. I want stability with a 24 inch lens in the field (minimal wind) and a lighter weight tripod than I've been using. I don't need anything over about 70 inches in height and do not need a center column. The info on the Gitzo website really doesn't offer much help in selection so I'm looking for a recommendation from the users here.

Thanks in advance and have a happy new year!
