And the final settings just got crazier (like I said b4 I wasn't able to fix the pregnant morph, but it does look more like natural stretch wrinkles than the crazy stuff that it was doing before), the new settings are:

Max Samples 100
Sym Samples 0
Distance Weight 1
Falloff Start 0.05
Falloff End 0.6

So thanks pjz99 so much for helping! :D
