If you are adding lead (or other weight) as ballast in the bottom of your model and you have options on where to put it is it better to have it close together or spread out as far apart as possible? Does it make a noticeable difference? I'm guessing having the weight more centrally located would make the boat more nimble or twitchy in its pitch and yaw axis while having the weight further apart would make it slower to respond to pitch and yaw input and to forces affecting those axis such as waves and currents.
being nimble in the yaw axis is a good thing of course but most models subs tend to be overly sensitive to pitch changes causing porpoising. I've always found it very hard to get a sub to stay at periscope depth for very long.
