First to get a better response i would put this in the growing part of this forum, just my two cents.

But my opinion is if they are treated like angles, get plenty of light, and are supported the right way, I think they will survive. I have personally seen a person almost completely break of a branch and somehow it survived. I think you not only have to be at the top of your game, but I think you have to be a luck bloke to pull this off.
