ETAR has my vote. I don't believe that you could shoot a representative number of bows from all of the bowyers there. Just on one side of one tent that we were located in (which is less than 1/6th of the total) there was Hummingbird, Striker, Dryad, Bear, Zipper, and 2 or 3 more that I can't recall the names of. There were probably 45-50 bowyers there and a lot of used bows. The blanket/yard sale each evening had more than a hundred used bows and equipment for sale.
It was also convenient to test a bow. Just outside the tents was a practice range which stayed busy.
I hope that you can come. We have some very good bowyers, and the environment there, both at the event and in the community is great.
