One other thing to mention (which I teach my students), is on a shorter field there is much less room to abort a take-off. I would much rather notice a light or malfunction while I'm stopped at the end of the runway vs. already rolling 1/4 or 1/2 the way down the runway... By the time you notice a problem, react, pull the power to idle and apply the breaks, it could be a little too late... Good chance you could slide right on off the end.
