One can give adequate attention to every instrument which can fit on a
glider panel, and many more.

For a suitable definition of "adequate", of course you can. I prefer
to be looking for other gliders, myself.

I find the radio useful for expanding awareness of those things which
are not readily visible.

It also has a tendancy to concentrate attention on the gliders you can
here. Accidents have happened - to powered aircraft as well - when
pilots assumed that what they could hear was what they could see,
