I attended the seminar too and despite being an experienced Commercial/Police/HEMS pilot, learnt a lot about a lot of things. It was good to pass on a few tips to some of the pilots that I talked to.
Perhaps the discussion group at the end should include a number of luminaries from the helicopter world (like Q and DK) so that they can pass on some of their experience to the majority of attendees who appeared to be low hours private pilots.
Even if this seminar lasted two days, there would not be enough time!
