That corkscrew tail filaree sounds like it. The leaves also have stickers on them, kind of like nettle. There's even a third sticker-thingie that they produce before the corkscrews. I used to have them somewhat under control until this year. I think the heavy rains triggered a comeback of them.
Thanks for the info.

Last year was the toughest weed control year I have ever experienced. It was also the greatest opportunity to use up the weed seed bank in many years.
