After reviewing what I have and what I need in the field, I realized that fancy new wiha handle isn't making it into my carry set up. I'll use the wiha 758 adapter with the wera driver when I need the precision bits, so only the precision bits and extension get included but no dedicated handle.

Next steps. I need to figure out how to store the loose bits that don't fit in the handle. Also, that harbor freight nut driver set really stands out as a space waster. The Klein 32933 and 32934 look like a really clever solution for that.

Here is where it stands.
