I seem to remember (although I wasn't directly involved) the RoKAF managing their fleet as they were getting close to the 6000 fhr (and maybe +10% granted) life. I'm happy to be corrected, but possibly these are the "best" airframes.
Interesting that DD says they aren't equipped with all the electronic equipment stated earlier, which makes them not much capable than the former 100 Sqn T1's. The Draken L159s have got radar, RWR and Chaff+Flare at least.
