Well, personally I can confirm your story about the choco fin on the Fanatics, although my experience is with bigger fin sizes.
I've used a choco 43 both on a Ray and a Falcon, a couple of years ago. Spin out all the time. Especially with the Ray.
The same fin on my Isonic122 and NEVER spin out. It could also be my style of slalom surfing. I like to put a lot of pressure on the fin.
