See a Youtube review of one of the 2 recently released head and tripods from Gitzo

Head -GH2720QR

Tripod - G2531LVL

From a Digiscoping perspective, i had reservations about one lock for pan and tilt, i found this not to be the case, and with a long Manfrotto plate for balance, (501LLP Long) balancing scope and camera were fine, for Birdwatching, a very nice head, Gitzo have always had a good reputation, the legs were surprisingly light even though they are carbon fibre, another choice to be put in the mix when choosing you next head and tripod
