Do it in the twin - wish I'd started ME flying in the CPL.........stick in the same one for the CIR as well.

StraightnLevel - for a PA31 endo have you tried at AF, there's one on line at AFTS. QAS (CDR) can also do them - John Eglen is the CP/CFI there (although he has been away sick a bit lately). Otherwise if you've got better than 250hr ME & a CIR drop me a PM & I'll hook you up with my mob.

C206/210
 

Druglord does have a point - along the way it might pay you to get 5 hours on a C210 as well. This is the aircraft you will almost certainly be flying at some point in your career and is many bush pilot's first job. You will put yourself head and shoulders above the other resumes if you have a few hours on type for the first job.

Still do the bulk in the twin though for down the track as discussed above.
