In May last year I blogged about replacing the head on my Manfrotto 055PROB aluminium tripod with relatively inexpensive Sirui levelling base and panning head parts. As opposed to junking the whole thing and buying a new expensive tripod. https://mikrokosmfotos.art/2019/05/04/upgrading-my-trusty-tripod/
That has proven to be a great improvement, and it’s such a better experience using it now for all sorts of photography.
The one lingering useability glitch has been the rubber feet. Unstable on carpet indoors, and on various soft surfaces outdoors.
Yesterday I replaced the rubber feet with retractable screw-out spikes.
The renovation of the 055PROB is complete. The Sirui head is wonderful, and now on spikes it’s rock solid, more than a match for my heaviest camera gear.
