Inbreeding is the guardian of outcrossing and to poddy-mouth it is incredibly shortsighted. If we do not have the foresight to keep lines and families separated around the world, then we would eventually have nothing left to outcross to. It would all be a related watered down version of what it once was and all it could be. Sound familiar(?), yes we've seen how that little experiment/scenario plays out before.
When we utilize intensive inbreeding, deleterious recessives are brought to the surface where we can detect/deal with/cull them, less intense methods only serve to mask/hide them, and do nothing to rid the population of them.
Using pools of parents pre-homozygosity is just slowly going nowhere as I mentioned before, or as Allard put it in the book Raco just gave us a picture of, "...such matings are of essentially no consequence in concentrating favorable alleles in selection programs in outcrossing species."
SSD would be a fine method to use, providing we could look thousands of families after many cycles, and combine/bulk the very best of them. But cannabis doesn't self without help, and gives plenty enough seed to utilize more appropriate methods.
What is rubbish is thinking we can reasonably expect a plant to pass on anything reliably in any hybrid cross, prior to (proving) homozygosity via such methods as observing the selfed progeny.
