I think that the deal is done now,so I'm gonna say "good choice". You seem to be happy with the knife and that's what matters.
FWIW, I have all of the knives mentioned by the OP except the mini-Pika. I really like the 14210 for my uses. I carry and use mine as much as I do my mini-Grip. I agree that the Caly 3 has some advantages in certain areas for me (grippier scales and I love flat ground blades), but that's just my POV and my preference for Spyderco knives.
I think you'll be happy with the H&K. According to STR, it's one of the most complete folders available (lock strength & reliability, blade steel, handle materials & construction). That's high praise IMAO.
