It only took 85 comments for JTG to get the answer on how to flat base. People seem more interested in fighting words than snowboarding advise. Somehow the topic of flat basing always gets heated.
Splitting hairs seems like a useful exercise in this thread, since it's clear from the discussion that different people have different definitions of what 'real' flat-basing is.
Looking at the video posted earlier, demonstrating 'real' flat-basing, it looks to me like that guy is actually shifting the weight a little between toe and heel edge.
