Linc,A pleasure to meet you in Dayton. Thanks for attending the presentation and I too enjoyed the chance to talk with other line array devotees.
When you present material like the near field line array stuff to a group (or have a copy of it on the net) then you have to adjust your presentation so that a large part of the attendees can comprehend what you have to say. For someone like you with a great deal of array experience it may seem to be boring yet for others it might be too advanced. The trick is to balance the contents to educate the largest share of the attendees.
We'll agree to disagree on curved arrays but that is what makes life interesting.
