Eesh! Some of you guys are slow, aren't you. How many times do I have to tell you...
don't carry your own tripod! Get a porter. Your partner will do (ideal, in fact) but you could at a pinch use a large dog. Last week I passed a small dog carrying the most enormous stick in it's mouth. I said to the owner "Can he manage a tripod?" and he looked at me very strangely...
The dog put the stick down.
And another thing... don't bother with all that carbon-fibre nonsense for lightness. If your partner or your dog (or even someone else's dog) is carrying it then why waste money.
Glad to be of help here...
