Another drag question

[joedog]

Ok I didn't want to confuse anyone so I'm threading twice on same topic.
As always I refuse to take the easy route or simple route anywhere so as usual I researced drags. When will I learn to stay inside the box?

Now this is what a manufacturing rep said. Always loosen the drag after every outing. He said you should back them off to almost nothing nightly and reset the next day. Incidently it was a Shimano rep.
I'll confess, I don't think I ever undraged a reel other than when switching spools, if that counts.
I do store them long term with drags loose but not nightly.
I can barely remember where I parked my car, I'll never remember to readjust the drag every outing.

Now lastly, is this really just a spinning reel technique or concern or baitcasting too?

So what are your thoughts anglers?
