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

yes, to all of it when speaking of Max Performance. But my point has been, when building "dirt road budget build" vehicle, and parts or being thrown at it and continued to be thrown at it, a custom converter isn't optimal for the budget because the changes would be enough to warrant "another custom" converter.
I've only skimmed the 7 pages of this mess, but it appears that folks are talking in circles. To your point made above, if you are throwing parts at a build, then it would make sense for you to just throw whatever converter you have at it, because you really don't care about maximizing your combo (ET and speed). For those of us that DO care about having a fast car, get a converter tailored to your specific combo or you will be leaving a lot of ET/speed on the table....its that simple.

By the way, this was posted in the RACE forum; therefore, I would suggest a custom converter everytime....if you posted this in the non-race area it might be a different story.
