Honest truth?? I would not use either mold. Knowing that you want to use a 3/0 Owner 5318 in the 1/8oz cavity I would use the CRJ-6-WBA and drill the eye out a little so the 3/0 would fit. The eye is only slightly too small. The reason is because I hate the lead barbs. I think they do a poor job keeping the plastic worm in place compared to the wire keeper. But if I had to choose between the 2 molds above I would pick the RHB-6-1816 because it is more on center and I believe it would do a better job. Also, you can pour multiple jigs at one time.
The flashing under head is result of the mold not quite closing because of the eye being ever so slightly too big.
