If you are referring to me, I don't have a lot more experience. That is certain. I may have done more reading.

Everything I have read says that a clone is just that, an exact copy of the mother and that you can keep it going into perpetuity. I have seen the posts out there that claim that this type of cascading cloning leads to less potent yields however, they are debunked by far more scientific sources. Sorry I can't point to them. I like to document when I make statements of fact. I'll see if I can dig it out.
