Two points:
Firstly, regarding Career Spine Sqn Ldrs. I thought I had heard (from a qualified source) that the rules for them had now changed, with effect from about 12 months ago, in that having made Sqn Ldr you were no longer assured of employment until 55, but now only until 44. Presumably there would be some mechanism whereby, having reached 44, a decision would be made on whether or not furthe service was offered? An assimilation board for Sqn Ldrs? If I am right this makes Career Spine Sqn Ldr potentially even less attractive. Can anyone out there confirm/deny what I have been led to believe.
Secondly, reference PAS and ground tours. I know quite a few PAS people in my world on ground tours, and there is a strong possiblility I will be one of them in a couple of years.
