I tried the tape mod with the L-cush for a while. Improved bass impact but significantly reduced the signature Grado airiness. Instead, I did the vent mod (punching the felt behind the driver with a ballpoint pen) and that did the trick. I'd assume taping up the G-cush would reduce airiness as well, and that's something that no amount of EQ can fix.
