Will likely be moving to a new house in the near future.

One of the earliest jobs will be putting up curtain tracks as neither of
us can cope with sleeping in rooms that are not sufficiently dark. Seems
to me that we should select one make of track and fittings and use it
throughout. (We might need to consider cording, and maybe a heavier duty
track in the living room with full length curtains. Ideally the same
gliders everywhere.) No bays or any other awkwardness to cope with.

What make track would you choose, and why?
