Picked up a couple spools of the MFC 6/0 at Lakestream as soon as we got into Whitefish. Great shop, btw; Rob Weicker has put together some excellent tying videos http://www.lakestream.com/category/fly-tying-videos/ He's going to be doing one for the Coffey Sparkle Minnow shortly, which should be nice. Anyway, the thread is really good stuff; the 6/0 seems to be about the same thickness as Uni 8/0 but it lays flat and splits easily.

Regards,
Scott
