The GS1000i is the most comfortable Grado I've worn. Its combination of jumbo pads that surround the ear rather than press against it and lightweight earcups, make it seemingly disappear. The PS1000 is the next most comfortable Grado I've tried, but as you say, its weight distribution makes it unwieldy. Definitely not recommended for vigorous headbanging.

Non headbanging with PS1000 it is strictly forbiden : you can hurt someone in front you...
PS1000 gest much much more comfortable with the ony manta headband on ( http://turbulentlabs.com/grado-onyx-manta/ )



























The Koss closed headphones are *sort of* similar too, like the DJ100 and R/80. But not tons of isolation. The quest for a closed Grado-replacements is a long-standing one, and I think the easiest answer is that you won't find a straight-across replacement. Just something that is also good, but different.
