Rotor bolts work well if you find the slightly longer ones, plus LBS will have handfuls of spares, probably mostly T25 but some 3mm Allen too.
T25 is far superior to a 3mm Allen key too. Especially for a dome head :)
They are, although occasionally they can be a bit fiddly if you don't have the range of movement a ball ended Allen key gives you in a tight space.
