160 - I'm assuming you mean multi-training approval??? (META??) Not initial twin - which is what I made of FTDC's post..?
Remembering you need about 50 twin command, and then 10 PIC ontype to excercise the privellages of a META - I'd say Duchies/Barons seem to be pretty common at the schools.
If you've got yer grade 1/2, plus the required time (as mentioned above) - perhaps try one of the larger colleges (I undertand FTA have a heap of brand spanking new twins on the way).....................
