From what I know from the Fall show (have not been there myself) is that for most collectors it is not worth it.
For the winter/spring time, there are over 40 different shows. For the Fall, there are 3, and the shows are also smaller than their February version.
Can not think of any dealer at the Fall show that could satisfy your modern chevron bead obsession.....
Just today, I have booked my 2017 Tucson plane tickets :-)
