I gave my rs5000 away – I got the Feedback Ultimate as it has the better clamp – they were called Ultimate – paid £220ish I think.
It is very stable – th tripod base is very tolerant of the ground it is on – and I believe a lot of pro mechanics use them on the race circuit.
It may be that other tripod styles, like the Topeak, are good as well for less money. But mine would have been cheaper if I had just followed my instinct and bought it in the first place instead of the minoura (which I got for £80 in a Merlin sale) and another stand b4 that.
a bit expensive but I can’t see me ever changing it.
Otherwise the rs500 could be made stable with a couple of sandbags on the legs – for a cheaper but less flexible solution.
