I didn't mention the bit holder which you remarked about in your first post. I liked the tool adapter but never used in an EDC scenrio but I allways have it handy in my truck along w/ a 100 piece bit set from black & decker. I've used that combo many times.
I'd really have to look at the bit holder closly because I like having the tools prementaly attached to the tool. It seems it would be very easy to drop a bit and then have to search for it. The original wave tool adapter gives you flexiblity but you still have a small tool chest permentally built into your tool.
The problem I find with multi-tools is you never quite have the perfect tool.
