I have seen racers run them because the allstar at their local track does and they are all over the place. It only takes one incident because you were running that locked diff to negate the advantage you had by running one.
To that all star, make sure you know the skill level of the racer before you suggest he run it. The worst comment is to tell someone is that "I see why you are slow, you are running a diff". Sometimes the diff is faster and I can tell you, ball or gear they are more consistent.
I keep all three available and know when to use them. Help others to know the same.
i think that mad rush for spools up front was about 10 years ago
