You're in for quite a wait if you want that Mike Roylance edition, according to the JW Pepper link you posted:

Tuba Book & CD not available until about 2018 - orders will cancel

I have been through the trombone method book (Randall, Mantia) a few times and I have the Jerry Young, Wesley Jacobs version which seems to be optimized for CC. I was wondering if anyone had insight to the Roylance version . Is it more inline with the Bb version? And yes, I agree waiting until at least 2018 to save $29.96 is a stretch but I'm cheap and willing to wait!
