I just got a RE Alpha 31 from their 50% off sale. I like the bag a lot as I'm digging rolltops right now, though still figuring out the best way to use it -- I also wish the various straps were removable.

Any suggestions on mods or pouches that work well with it?

I have a Swedgie from Skinth on the way that I'll mount to the bottom as a kick stand, and I also got some org kits on sale. I've found some pouches that fit in the torpedo pockets, though want something that divides the space in two.
