Through experimenting a little, I found it wasn't so much about how much
weight you added, but where you added.  Even on the rear, if the weight is
over the rear axle, it didn't seem to do much to the handling except make it
tougher on hills.  Adding weight in front of the axle tended to increase the
self centering and enhanced downhill handling and speed.  Weight behind the
rear axle had the opposite effect.

The python is quite the interesting beast when you start looking at the
dynamics and interaction of all the small changes.
