 I would go with (1) or (2). The Legacy is very fast and very  slippery. It
does not like to slow down. I have been doing my lessons  in the factory's
(Legacy which does not have them). When you pull  back on the throttle you
need to carefully plan your distance to  accommodate the slowdown time. The
speed-brakes will significantly  shorten that length. I read that you can land
with them on, because  at landing speeds the speed brakes do not appreciably
affect the lift  characteristics of the wing.
 
 I am getting them!
