The length of the rod has got nothing to do with the bite point. An hydraulic system is self-adjusting - the slave piston will move out until it takes up all the slack and then begins to operate the clutch. If you have a longer rod all it does is mean the piston operates over a different range. The point of the different length rods is to accomodate two lengths of slave cylinder, and to make sure that the range of movement is not too close to the end of the bore risking the piston popping out.
