You will be very hard pressed to find the hooks that the bent rods jigs are using, but I wish you good luck. I tried for a while and finally gave up. There are some other heavy jig hooks on the market if you do your research and are willing to purchase out of the states.
The hooks in question are not a regular catalog item and may not even be available on custom order from what I have found. I contacted several sellers through ebay who were selling other matzuo hooks but they could not supply the heavy gauge jig hooks in 60* or 90* configurations. I did find a distributor that sold the large brass and silver beads that the jigs employ I will see if I can dig up the link later.
You will find threads on some other forums trying to track down appropriate jig hooks as well which may yield some useful avenues to pursue.
Retail wise you will only find the bronze or red hooks that are nowhere near as heavy gauge and are not that useful for tying jigs.
