Interesting thread.
After doing a comparison between the Battlefoam Malifaux bag and the Sargent Portable Warfare bag, it seems that the Portable Warfare bag is the better bang for the buck. It seems there would be more square inchage (is that even a word? lol) with the Portable Warfare bag, which, cost with shipping for those of us in the US, is roughly the same as going with Battlefoam.
Seems to me that I shouldn't have an issue getting the 5 crews that I've accumulated, avatars, decks, books, and possibly all Puppet Wars stuff to fit all in the Portable Warfare bag. I really like the fact that all the trays are pluck-and-pull style for ultimate flexibility.
All that being said, I need a bag to store all my Malifaux stuff and I think I just got sold on Portable Warfare. Thanks for this thread. And thanks Ciaran. ^.^
