I would suggest starting out with exactly the same VOLUME, not weight, of balloons to resin. Pour equal amounts of resin, by WEIGHT, into two different containers. Add, by volume, equal amounts of balloons to each cup. Stir both to get the balloons well mixed, then combine the two.
A 100% by volume mix should provide plenty of floatation.
If that's not light enough, you'll have to go to a foam.
