I'm not a big filter guy, but I do have some MCP's and ND filters in various strengths and sizes that I pack around. Probably 8 in all. Their individual cases/holders take up quite a bit of room in my Lowepro 400 AW. Is there an alternate way to pack these around where they won't get scratched, and are easily accessible, while reducing the amount of space they take up? Thanks in advance for your help.
