The Manfrotto 161MK2B is fully capable of a 44# load, nearly twice any other Manfrotto product, It has massive tube diameters and independently adjustable spreader arms. Built in Spirit Level and self-locking 10" elevator column. It DOES NOT HAVE retracting leg spikes. No tripod has retracting leg spikes. It does have retracting rubber tips which expose the spikes. (Why does every tripod manufacturer get this wrong???) Total height is over 100"!!! You will need a ladder at that height. Heavy @ 19# but Best in the world.
