I use VMC and Gamakatsu. Usually use the open eye. Sometime's it's hard to find them. You just need to be SURE you crimp it closed all the way.
Try this place I used them a couple times.
Cabelas sells VMC. I use size 2 on Top Guns, size 4 on MLW, and 6 on DB's.
Also KTP sells Gamakatsu.
I just changed all my trebles over to siwas hooks made by Gamakatsu. Size 4 for Topguns, mooselook and db's...size 6 for guide's specials and 8's for little guides. All the research and review reading I did led me to gamakatsu.
Kittery Trading Post has them:
and Captain Hooks warehouse has them:
