I like these much more than the Fish Skull shanks. The wire size is the same, the lengths are true, and quality is high. The eyes are smaller, which will give you almost 1mm more of tying room, which is critical on the 10 mm or smaller shanks for gamechanger flies. If you are having trouble getting all the material on a 9 or 10 mm shank you can go up to an 11 or 12mm shank and not make your fly that much larger. (With Fish Skull the next increment is 15 mm.)
Also consider the 9mm in place of the 8 mm micro spines for small gamechangers. Much easier to tie on.
