I added a molle pouch to my 200, got a 2 pack off Amazon cheap, never seen a bottomland molle pouch, mine are multi cam, I used a single one for my pruners, probably add a second smaller one to the existing one, it has loops built into it.
I am looking to add a strap for pot calls as well, have not found anything yet. I have some small stretch cord, just nee a fastener.
