Oh Bobbi, you can ask a tough questions!

What would you consider the perfect amount of stash?

Perfect amount of stash.. If you ask my DH  2-3 kg would be enough.. and my answer would be.. as long as the stash does not hount me.. the size is perfect.. at this point I think it'll mean app. 30kg yarn.. ( ps. don't tell to my DH)  :D
