one of the reasons I got a systematic tripod was because I found out about this upcoming product. http://www.vistek.ca/store/ProPhotoTripods/238742/gitzo-centre-ball-head-systemic-series-35-qr.aspx it seems to be available now but elusive and hard to find, even on the internet. I cant find any reviews, or any US dealers with stock. BH is the only place I have found that even lists it and its special order. has anyone seen one of these? touched one? know where one exists? Know if it will become more common at some point? It looks fabulous on paper. installed on the tripod, the ball will be very close to the vertex of the legs since it really sits into the systematic hub. combined with the hydraulic lock and nearly symmetrical design, it should be really easy to use as well, with not need to spin the head to orient the knobs. I have read contradicting info on whether the QR version is arca compatible. just trying to get a feel for this thing.
