Okay Willing, I tried to work it out and I can't get it as smooth as you got it. But on that 7-3-6 progression I came up with this
C7 / Cdim
F7 / Cdim
Bbm7
Maybe if I work the vocing out a little different I could get it a little smoother. I need some guidance on the other progression.
Let me know how I did.
