I got the Orion 2 base in July 2023 I use it with max stick extension and the Cam Kit.
On the stick I use the heavy springs on one side and the dampers to the other.
After ~9 months one of my spring broke, the other is deformed in the same region.
My Spring dimension are 1mm wire diameter, outer spring diameter 9.1mm, length of unstressed spring ~27.4mm
This one came close:

Okay they replace just the one broken spring, they don't send me a second one even if i pay, but I can buy a second cam set
