Which is the best helicopter for training?

[ALM In Waiting]

Hi All,
I'm new to the rotor heads forum, but have a couple of questions about R22 vs G2, and can hopefully get a broad range of advice on here.

I am very much an absolute beginner with a 1 hour trial lesson on the R22 completed and nothing else.

I am looking to do my licences and be in a position to start a second career as a helicopter pilot in approximately 9 years when I leave the RAF. I am aircrew but not a pilot.

Firstly, is there likely to be much work out there for G2 instructors in the future, or is it likely the R22 will remain the most popular training option in the UK?

Would someone who had mostly G2 hours be considered as an R22 instructor with minimum hours and quals on the latter?

Would someone who trained on a G2 find it harder to convert to older airframe types? Eg non glass cockpit etc

Thanks in advance for your time.
