I don't know the exact current std. of practice but they do research on what is effective on what sub-pop'n all the time. IIRC, the fecal thing was not so great.

My understanding is that Tobra gave it to you straight.

If you do not like the std.s that the GI guys have come up with and think they are just money grubbers, you can certainly submit your own research results.
