With thin CA, you assemble the joint dry and make sure everything is aligned, then you apply the glue to the assembled joint. Capillary effect (surface tension) sucks the glue into the assembled joint where it hardens almost instantly. Think of a plumber sweating copper pipe fittings with solder and you get the idea. When gluing balsa, the strength differences between different glues is a moot point. Break a balsa joint glued with CA and you will break out the wood next to the joint.
