Without breaking the bank on a carbon fiber tripod any suggestions for a good tripod for hiking....think light weight? I currently have a Manfrotto 3405, unfortunately the head ( #390 ) isn't removable. I believe that is the draw back to this model....has anyone ever cut the head off and placed a ball type on the centerpost and be secure?? I like the twist lock legs that I have now as they are easier to stow in the pack vs the cam or knob style locks. Suggestions???
