is it a good idea to shot an overdraw on the fita field round or does the shorter arrow fly less stable at those distances?

As long as the arrows are spined/tuned correctly they will all fly the same...
As for an over draw, it may not not be an advantage (I haven't shot a field round) but its mostly a speed inducing device nothing else...Although it does have a tendancy to make the bow less torque resistant.
