H500,
Indeed, your idea was good, you've done the maximum you could. They're still too small.
As you don't want to take any risk, two years are perfects for you : more than 100 G2 flying, more than 100.000 hrs and a fleet leader with about 3000 hrs. the G2 will still be a very good aircraft as it is now then you will be able to say : GO !
P.S : mind in which bank you put your money in the meantime ...
and fortunately for you, you're waiting in a old but good aircraft
.
