Smokin,
It's 7 years from the expiry.
TU,
FWIW I'd suggest sticking with the established IR schools (Bond, Bristows, PAS/SAS, Helicopter Services) (with apologies if I've forgotten any others) if you decide to fund one. They have fine tuned their training and have proven results,not to mention offshore contacts, that newer companies expanding into this area of training don't. (In no way a dig or negative comment about the new guys on the block, but for the money involved I wouldn't want to be their guinea pig). One of the 4 I've listed does a lot of initial IR training for CHC -providing a well deserved 'Helicopter Service' IMHO
Stop worrying about the TT and commercial experience/ turbine hours.
On shore commercial Ops in singles is completely different to offshore flying (so I'm told by Helimutt

), P2 in a twin anywhere is also a different kettle of fish to a bit of Jetranger time.
You'll need a lot more experience to get an onshore twin job as a P2 (and a whole lot more to get P1), and at your current stage an IR would be of far more interest to the big 3 than another couple of hundred hours in a Robbo or JetRanger.
I FI'd for a while, before funding an IR and it was, and still is, the best move I ever made

Good luck
