Im a bit surprised by this thread. More so, that the people on here arent more familiar. Admittedly, I am not personally experienced. My best friend was doing this at least 5 years ago, at one point this was his sole method of propagation.And he said it was more consistent with NO genetic drift OR possibility of transferring pests or virus. He had previously had some problem like PM or something and this is how he "saved" his genetics. He showed me his TC setup and clones many times and also explained(in quite depth!) how he made his little "sterile"box and the entire process. However his affinity for smoking lots of blunts(and the fact we were in a warehouse that he was living as well as growing in) had my attention span shorter than the required amount to take in something like TC. He is NOT a rocket scientist (although does have a small BHO lab !) but he did have it locked in and said he got to the point were he never lost a "plantlet".
