jack_k: that's exactly why they'll go first. The idea is that 6 will reform as one of the first two front line Typhoon units, leaving 11, 16, 25, 41, 43, 54, 56 and 111 to compete to be the numberplates for the remaining five or six Typhoon squadrons (complicated by the fact that 3 Sqn is almost certain to take one of these slots after it loses the GR7).
If you're feeling really bored, the thread about disbandments and numberplates gives hours of endless fun explaining all of this. If you browse it, remember to don an anorak!
