Aleph 3, 2xJSB123 with a RipOff CO-85, my newest pouch. It's a bit big but may work just fine for my BE4, 2xPila 168S which is on its way.
A RipOff CO-130 works with a Aleph 3, 2X123 but the flap just catches. A RipOff CO-130 will handle any McLux PR/PR-T 2x123 with a bit of space still at the bottom and might be perfect for a BE3 which I don't have.
The CO-85 is padded whereas the CO-130/131 are ballistic nylon.
Also new, is a CO-150 which is padded. A PR-T, 1x123 with a two stage switch slides in and even the head seats down inside the padded area also. The above mentioned CO-130/131 hold a 1" diameter of a 123 powerpack and the CO-85/150 are bigger, where a PR/PR-T head will fit inside.
EDIT: I corrected the above to read that a Aleph3 works with a RipOff CO-130 but the flap barely catches.
