NLCASH how do you guys feel about playing shorstacks?

so what do you guys do when you get a 40bb guy grinded down to like 25bb or lower (because now it is essentialy like someone sat with 25bb or less and according to most of your guidelines you don't like playing that short).

But if you sit out at this point it is like you were just taking 15-20bb off the guy in the case you didn't stack him for 40bb but just grinded him down a bit. To me it just seems annoying to spend time playing someone this short when I could just open up another table and use my time better, but as you guys said often these bad guys will buy in for more when you bust their 40bb, so maybe it is best to just try to finish them off and see what happens?

I'm interested in having an efficient bb/100 and since I do not have much exp playing headsup was looking for some thoughts in this situation.
