"Weight doesn't affect glide ratio" is one of these things I learned why taking flying lessons that still feels counterintuitive every time I read it.
(Don't worry, reader, I never intended to get a pilot's license.)
So, 2 gliders with identical geometry, one standard and one made of lead will have the same glide angle? That sounds unlikely.
