Very interesting bathroom reading material here.
PGP, Good investigation and you are doing more of a service IMO than a dis-service.
Bottom line however is that the only thing that matters in the end is the results,and both SMG and H&W produce some of the best results out there.
If we took graft counts out and judged strictly on results compared to price of procedure H&W and SMG would still be at the top of my list.
