Just something I've experimented with a bit...I've found that using a small pouch doesn't seem worth the 2 extra rune essence. The time it takes to load it and unload it, while it might not seem like much, makes it so that using it can even take longer than just using med and larger pouches. I haven't tried just using a small alone, but my guess is that would be even slower. If you had to choose between going with no pouch or using only a small pouch, going with no pouch should be faster. Example: I timed myself doing a load of Law rune crafting. Did the exact same thing both times (didn't use run to be consistent), so timing should be as accurate as possible. With small pouch, I made 43 in 4:54 minutes, for an average of 8.776 laws per minute. Without small pouch, I made 41 in 4:40 minutes, for an average of 8.786 laws per minute. It's a very small difference in this example, over an hour period you're only making one less with a small pouch. Still, it is a difference, and can be noticeable with some places or over long enough peroids of time. This could go under pouches or under tips and tricks.
