I have limited experience, but after reading several articles and forum posts, I decided to prune mine back over 2 years. I left foliage on every branch and just waited for back-budding, then pruned again.

I would agree with this... I have several in grow pots. Is a 50 / 50 shot if it back buds if you cut all the leaves off branch. When I cut two of mine hard backt wo years ago not leaving leaves on some of the branchs half branches budded back and half died back. This is just my Expereice.
