Couple other thoughts re coasting:

1.) At least with a wheelbarrow, big wheels push easier than little ones.

2.) Wheel inertia, disparaged under power, especially when needing to frequently brake, is not necessarily such a detriment when largely coasting up and down hills in our area.

Particularly if the wheels are storing energy by retarding speed which might be wasted in braking at curves, where speed buildup downhill otherwise would get excessive with small light wheels.
