OK Chris, I believe that we are both saying the same. I said, or tried to say, that large pouches produce more air friction in the turning around and launching, and that even accumulates air pressure (in the launching, not in the turning around) that makes difficult the aim due to an irregular behavior of the pouch in the firing. If we pay attention, the pouch in the launching catch air pressure, and is that moment the important one, since it is when the true acceleration is developed. Splits or holes in the pouch point to avoid this effect, although I agree with you that some Andean slings, mainly the present ones, use this design mainly to obtain a better adaptation of the projectile. Nevertheless other Andean archeological slings have a pouch completely divided in two parts, just like the Balearic ones, that look for the effectiveness in the firing and accuracy by avoiding the effect of the air in them. There are others in mesh form that also persecute the same effect. In general it is a good idea to avoid large pouches, even to send big projectiles. I remember that the Romans used a simple narrow leather strip to send stones of one pound, balancing the projectile in that special sling which they called "librilis", in concordance with the projectiles of a pound that used.
