  Saab 37 Viggen (In all configurations: Figher/Attack, Attack/Fighter, Ocean 
Recon, Photo Recon and 2seat Trainer) use thrust reversing.
  The reason is that it has to come to a full stop in a very short length of
runway to fit into the Swedish system of basing the entire airforce on 
slightly modified roads...
  I would guess that the entire apparatus for reversing thrust weighs a lot,
and this weight will be dead weight in the air.

  Saab 39 Gripen (JAS-39) is said to use high-efficiency brakes to achieve the
same goal without wasting that much weight.
