What's everyone using for their void filling pillows? Tab, armageddon, weibad, etc? Mainly for when your pack is a wee bit too big but you got some space to fill up.
I don't use pump pillows anymore, but when I did I used a modular pump pillow from WieBad. They make great products, and I continue to support them (love their mini fortune cookie!).
Traust makes great products as well. I haven't used their version of a pump pillow, but I have been rocking their rear bags latley.
