Thanks for that article, it has some items that I want to think about. Dr. Bamforth has said more recently that HSA is the last thing that a homebrewer should worry about, as there are other things in the brewing process to get under control first. The yeast will also clean up most of the oxygen products, so he said a good healthy fermentation will take care of a lot of problems.
I have brewed Joe and Andy Hudecek, who pour and splash with reckless abandon. Their beer turns out to be very good, and will win awards 6 to 9 months later. They do have some of the freshest yeast that you can get when they ferment. This has made me less paranoid about splashing on the hot side. I still try not to abuse the mash or wort on the hot side, but a if I have to do something to make the brew day go along, so be it.
