I have come to the conclusion that stall speeds and other attempts to quantify torque converter performance are pretty much meaningless when it gets down to the the fine details. Either the converter works with your combination, or it does not. Loose, tight, etc. are pretty much useless other than in describing the converter in your combination.
The best converter is the one that works with your car and the best manufacturer is the one that makes a good guess at your needs and then is willing to alter it so it does what you expect if it is not right.
You probably will not be dealing with the vendor/builder that is the internet flavor of the month with the kids on the forum that form his posse and it won't be cheap but it will be worth it.
