Both molds call for the Eagle Claw 570 or 575 jig hooks, pretty much a standard for most basic Do-It products. You're not limited to EC hooks though. I've substituted (at one time or another):
- Gamakatsu 114
- Matzuo 9014
- Mustad 32746BLN
- Mustad 32756
- Sohumi 105
- Sohumi 103
- Daiichi 4660
- VMC 9147BZ
- I'm sure there are others...
Honestly I like Eagle Claw products. The only hook I know of that is US made. Sometimes not a sharp out of the box and certainly not a sexy brand but still great hooks.
If you're new to casting jigs DO provide adequate ventilation. Always take the time to make sure your hooks are properly placed in the mold. The mold should close easily on the hook(s). If not open it up and insure they are all in their places. Forcing a mold closed, even a little bit will booger it up and there's really no fixing it once you have.
