I've taken to carrying two can stoves myself.. I've got one pressurized stove for full out boil, and one sort of penny hybrid design.
The hybrid stove has a 1/8th hole in the middle/depression area of the top, to fill with, and then six needle sized holes on the ring. Lit normally, it produces around a medium-low heat, great for light sauteing, drop a penny in the middle to cover the center, and it drops to a low simmer, great for finishing rice after boiling the water initially..
Best solution I've found yet personally.. A little extra weight, but no parts to lose, and real tunable combined with an adjustable windscreen.
