This is my first comment on someone else's rack so maybe take it with a pinch of salt!

I think Pam's a a nice choice here because I'm assuming you intend to use it to modulate the BIA to extract all them sounds, right? Plus you can self-patch it for 2 layers of modulation. You could maybe shave a few HP with a more narrow 8HP Plaits clone and get a 2HP Turing and wouldn't you need the 2HP left over for a mixer?
