Efficient way to create kits with perms

Hello, im not with my computer right now but im currently working on a solution to this problem, my idea is to create a list for each kit and check if the player has the permission before they can receive it. however, i dont want to hook it up with permissionsEx or anything so im wondering if there's another way to store the players kits?

Or would i be better to save them in a map and save that map to a config? I have recently learnt custom configs and have made a stats file

You want these permissions to come from pEx?
If not, you can define plugin specific permissions. After that it is as simple as making a command that gives the kit, if player has said permission.
