I dumped venting the Fostex. I'd like to keep it closed.
Okay, here's my current setup: My yummy sandwich pads
I still can hear the ugly bass with the synthetic leather and prefer the bass with the stock pads on top. I also like the sound|feel|look of the 'inverted stock pads'. You may want to try it yourselves :)
and super comfy headband
Next will be further tuning of bass and extending the treble a bit more.
