Although I have never flown one, a Jabiru may well be quite demanding, but how many GA Chief Pilots would know?
Time in the type that you are most likely to get your first job in is probably more important. Suppose two wannabes come in for interview, equally presentable and equally personable. One has 300 hours total and 30 hours Jabiru. The other has 275 hours total and 15 hours C-206. We have a 206 parked out front ready to go to work earning revenue. Given that the difference between 275 hours and 300 hours is bugger-all in the grand scheme of things, as CP I would probably favour the pilot with 206 time. Simply because it will hopefully mean less training time at induction.
So, can a 206 be rented for near enough to twice the going rate for a Jabiru? Round up some mates, dry hire a 206 and take them on a fishing trip, sharing expenses. Drilling holes in the sky in a Jabiru or anything else is pointless.
