FE1....you are correct it is a single pour. Pain the butt. TXmedic you may have older model. They came out with your mold with wire keeper.
Let me know if you need a pic....it now has the section cut for wire instead of being a mod. RonDons are from CrazyAngler and I think he retired from doing mods. And RonDon is getting addicted to pouring plastics now!!!!!!!!!!!!!!!
I think the mold mentioned above will work just fine. 2nd option is below.....that model teardrop style with 1/16 you can run a #2 or #4. The 1/8 can run a #1 down to #4.
