I will say, the only work my cast iron requires is cooking a really fatty food in it once a month.... my stainless pans require scouring if I do some searing (even with a good deglaze) which is a huge hassle. My cast iron, I just wipe out lightly and never scrub. I have never noticed adverse effects from this and it's well seasoned.
I do hear the weight complaint - I'm a big guy so it's not too bad but my girlfriend needs two hands.
