.44-77 and paper patch?

[Distant Thunder]

Ok, I've got it all lined up to have my Green Mountain 17 twist barrel put on my Shiloh 1874! Now the next question is......, the chamber? Do I go with a standard gg chamber and a 2-diameter paper patch or do I go with Orville's 7* pp chamber and a bore diameter bullet. I'm happy either way, but I'd really like to hear from those familiar with this cartridge. If you have experience with Orville's chamber then I'd really like to hear your opinion.
This been a bit of a struggle to get to this point, communications being so slow with this internet thing, but I am happy with where it's at today.
