Rick...
For the smaller say 3oz and smaller Ultra Minnow Jig Molds Ive been using the Gamakatsu in the 7/0 size with pretty good success...You may have to modify the eye location but that's about it.
I couldn't find the site where I got them last...the 7/0 is hard to find...last time I needed them I emailed Gamakatsu and they forwarded me a sight that had that size...I bought 2 packs of 50 each...
