I guess I don't see how the extra weight is going to help. It's definitely going to increase the rolling resistance, and I don't see how it'll improve the P&G efficiency. Sure you can glide longer, but it'll take more energy to accelerate the additional mass. More energy out only because of more energy in.
You can still P&G going down a hill, just accelerate faster so the %load stays roughly the same.
