Thanks guys. Yesterday I went to the local camera shop and looked at several tripods. Personally, I don't feel that the tiny weight savings is worth the cost. After extending the legs on several models, I didn't think the CF was much stiffer. I hike with my tripod once in a blue moon. And don't fly, so luggage weight is not an issue. By getting an aluminum tripod I can save enough money to get a nice ball head for it.
