Here is the Giottos website (http://www.giottos.com/) where you will want to go to the professional tripod systems and then to the MTL9 Series. They have good quality info there. They make the higher dollar carbon fiber versions as well but they jump up in price of course. They also make some pretty nice ball heads but I opted to go with a less expensive manufacturer that works great. Might pick up a Giottos ball head in the future as they look very nice and if they are built like the tripod then they will be a definite deal.
