Steam mount for GoPro (+ Wahoo)

Equipment
1

Good morning folks,
NBD Day is close (BMC TeamMachine Four) and so is the addition of a GoPro 13. I’m considering mount options, and ideally I’d like something to quick release the camera easily. This is what I got so far, and I’d love hear more experience GoPro users’ opinions:

  1. KOM CM06: Pros: easy to unmount, cheaper Cons: not a forward mount, flexy? Recommended by Ben Delaney
  2. KOM Stem Mount: Pros: easy to unmount, flush Cons: slightly more expensive, “adjustable” - which should be a pro but maybe makes it more flexy even if it’s aluminum?
  3. K Edge: Pros: really good reviews Cons: very expensive, no quick release - I’d need a GoPro magnetic latch
  4. AliExpress Mount (I’ve had good experience with ZTTO): Pros: the cheapest, like really cheap. Cons: Sketchier re: robustness? I’d need a GoPro magnetic latch for quick release

I’m leaning towards the KOM stem mount, but I’d be happy to hear your opinions.
