Good to hear. What do you like better? Do you have any pics comparing the two?
I had the ST-125, but have never used the ST-124. I ordered the ST-124 but CLNY didn't have any so I took the ST-125 as a replacement.
The ST-125 seems really well made. Definitely more bling or Gucci than the SLIK., on the surface. The SLIK is just plain Jane.
The ST feet have built-in spikes that retract, the connections between leg sections are "waterproof" and easier to clean than the SLIK. Spring loaded adjusters too. Those are actually nice features and not just superficial. I also liked the center column.
What I didn't like is all the racket the ST makes. The feet rattled and could not be eliminated with adjustment (in or out). Just picture setting up your tripod on a perfectly quiet morning or evening, and you move the tripod a bit or adjust the legs. Instead of being quiet and stealthy, the feet on my ST rattled. Not super loud, but I have been busted by deer at 600+ yards just from moving my boot slightly in gravel. The tripod foot rattle was more than annoying for my needs.
Same with the spring loaded adjusters. They sure look Gucci but make a racket too. I don't want metallic clicks and clangs when I am setting up or packing down.
The above complaints may not matter to everyone though.
Although the SLIK internal leg stops are not as convenient to clean and reinstall as the SIRUI, the sections have less play in them. Especially as you extend to the smaller diameters. I know the 5-section ST-125 is not apples-apples to the 824 but SLIK doesn't splay out as much at the connections. The SIRUI internal stop pieces are more robust though. The SLIK are like shims. Just be careful you don't lose them or damage when re-installing.
SLIK also has a wider stance. Same deal as shown in the S&S video comparing the 634 to the comparable SIRUI.
I do have pictures somewhere, primarily showing leg angles. I won't be able to get to them until the weekend though. Hopefully the above gives you an idea.
