Final answer:
You should take one of the weight pouches while your buddy carries the other to the surface, since they are heavy.
Step-by-step explanation:
You should follow your buddy's plan and take one of the weight pouches while he carries the other to the surface. Since you have both realized that the pouches are heavy and weigh more than 8 kg/20 lbs each, it would be challenging for one person to carry both pouches. By distributing the weight between the two of you, you can make the task more manageable and increase the chances of successfully bringing the pouches to the surface.
