YPC 62/81 and headjoints

[concertmaster3]

Hi everyone,

I wanted to inquire to see if anyone knows if any other headjoints work with the YPC 62 body. I would love to try out Hammig or Bulgheroni headjoints especially, but want to make sure they'd actually fit before paying for a trial.

Also, has anyone had any experience with the YPC 81? If so, how would you compare it to the 62?

Thanks!
