Has anybody tried the carbon tripods made by Velbon (Carmagne 630/640) or Manfro tto (Carbon No. One 440/441) for supporting LF equipment of moderate weight (e.g . an AS F-Line with focal range between 75 and 300mm)? The B&H specs for the carmagne tripods look rather impressive (B;can support25Lb sB+ at 3Lbs weight and below 50cm packed length) - is this just marketing hype?< br> Manfrotto specs are much more conservative (supports up only up to 11Lbs at simi lar tripod dimensions, and is shown only with an MF camera on top of it in the f lyer)...

If you do use those tripods, did you notice any problems regarding robustness/qu ality? How compare Velbon/Manfrotto carbon tripods to those made by the carbon p ioneer Gitzo?
