Go with 4 g tabs instead of 14 g tabs. It is even easier to sort out almost exactly how much fuel you need, so no need to burn a tab, then blow it out, then repackage it one way or another. Plus, I find that the 4 g tabs do not stink near as bad as the 14 g tabs, and they seem to leave less soot too!
However, they are harder to find, and the 4 g tabs are (usually) about twice as expensive as the 14 g tabs.
Or you can just split the 14 g tabs. I would suggest doing this at home before leaving that way it is already done, and one less thing to do in the field.
