why a custom built converter isn't for everyone....

It’s ok to do what you are doing. What is crazy is trying to convince everyone that any old converter will get the job done. I can tell you from 40 years of experience the number one killer of performance is poor torque converter selection, flowed by bad cam choices.
LOL... I only referenced "for me". Who is trying to convince anyone?? I only stated why it wasn't right for me. Who said "old converter"? Not me or anyone else that I've read.. .LOL Man, talking about adding, subtracting, or being delusional to hear, see, and read things that were never said, viewed, or written. LOL :D
