I had issues with my Lee production pot and a 2 pound Rowell ladle. Then I bought a bottom pour Lee pot. Then I bought a Lyman one pound ladle, and that is what I use now. I found that some molds do better with an easy pouring motion, and some want the stem of the ladle inserted and forced to fill. Weird I know but it is the way things go. The bottom pour might work but it might not. If you still have issues consider a Lyman dipper. Huge hassle having to clean lead off the hook and go for the big re-pour.
I wondered about the 14 cavities with hooks and wires and such. I would lose any speed advantage 14 cavities presented due to fiddling and bumping it and having to refiddle a few.
You mentioned it poured very clean, but the pictures on their website show otherwise. I was surprised to see a CNC mold with those type of results. Glad to see you are having better results.
Maybe they will bite this one……
