You are accurate, we are at the point where getting a return on whistling is not only likely but almost garenteed. The question comes does a crafter want to deal with a whistle based approach. That is the catch. Personally I'm not certain how I feel about doing whistling even when its optimal. There are a number of cludy issues I have with it. None the less I may give it a try this patch just for flavor. Maybe make a video of it for poops and giggles.
