I don't like multi tools except for the tire levers. Whenever something needs attention on my bike its like the only part that a multi tool won't reach or work for. I carry a star type allen wrench with the 3 most common bike sizes and then a regular set of allen wrenches in metric of course and a couple of screwdrivers one slotted and one phillips and a pair of small needlenose pliers and and some smaller size metric open and box combo wrenches. Sounds like a lot but they don't really take up a lot of room since they all seem to fall to the bottom of my panniers anyway.
