Just for information, don't assume an integrated course is shorter than modular: the whole course is, within a few weeks, the same length (modular is not to be compared with the old CAA "self-improver" route). As discussed some of the modular can also be done now, even if it as you are waiting for release, so shorting it to the quicker option.
Secondly don't assume just because you are in an important position you cannot be made redundant if you want to. A friend of mine was a qualified Sea Harrier pilot (just retrained from rotary) when one lot of volunteers was asked for. Everyone said he had no chance, but he and one other put in, and got it!
It was a numbers game, MOD bureaucrats didn't care who went.
If you want the redundancy, go for it! Start flying while waiting, then when you're outside start full-time modular.
Good luck!
