...So what do you think the most important,
still-outstanding and unresolved design problems are?...

Beetles come readily to mind. Not that I think they're undermisrepresented
as a food source......they just aren't that important compared to the
aquatics.....or that there aren't already enough effective patterns
around.....plenty of very useful deer hair and foam bugs to chose from.
But, deer hair is fragile and quickly soaked, while foam holds all the
aesthetic appeal for me of a bag of pus.
