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

I'll bite. I think people are going to do what they want regardless of anybody's opinion. I agree that it may not be necessary for playing with stock or fairly stock parts, but it wouldn't hurt. I went after a custom converter from Dynamic several years ago. It was the most expensive transmission part I bought, but I feel like it was worth it. I went over the engine combo, weight, rear gear, tire size, everything they asked for and they picked what they believed was best. As soon as I get that thing going, I'll find out how well it cruises and behaves on the street and the strip.
