Spirit is a great choice and a wonderful multi. IMO, the standard Spirit is better than the X - the serrated blade is excellent and is complemented very well by a small SAK. And I wouldn't bother with the plus versions either. The wrench and ratchet aren't worth the extra - you'd be better off getting a Topeak Ratchet Rocket or similar.It's much lighter and easier to carry than the SwissTool and very capable. It feels like an evolutionary step along from the SwissTool, not just a smaller version. Even the scissors are great.
Big fan of the butter knife here!Rather than either of the Vic bit drivers,I'd opt for a LM Universal Adopter,though even the standard one will do at a pinch.
