No disrespect meant, but just make sure you know how to use whatever tools you take. For instance, a spoke wrench is a neat little gadget, but pretty worthless if you don't have some rudimentary knowledge about changing a broken spoke/truing a wheel.
Also, carefully weigh the potential for needing a specialized tool vs likely access to a bike shop for more esoteric failures/adjustments.
Consider taking a temporary Fiber Fix spoke, and an extra tire tool or two in case one breaks.
