With the banning of forestry backpacks, carrying items while mining items is limited. Would it be possible to make enderpouches the "Large" size as the are in other mod packs. Enderpouches are much more server freindly than many other storage options since the only are activated when they are opened. I personally like since the contents are not lost on death, just build another chest and you get the items back, or use the chest to access the.
They have different sizes :O? You can always use golden bags of holding and the redpower backpacks; those are the two I use. Also.. Tinker's Construct has a very handy item called Knapsack.. This is my favorite
i use to use knapsacks for holding all my tools until they started to bug out on me and tools would just disapear.
Knapsack are a slotted item, sorta like a chest piece of armour. Changing the config does not break anything. Id Say go for it and set it to max size. Multiple golden bags leads to massive ticking players as they are stored in the player data, ender bags/chests are a separate entity from players.
