Capt Tired,
There are SO MANY agents involved in this contract that its hard to know who the 'best' is.
Most guys speak pretty highly of Longreach China and GABS. They seem to be very proactive in tackling the issues. My peers at least seem pretty unimpressed by the services(or lack of) from PARC and Rishworth. Seems that they work on the 'once your in and we have our money then we dont care about you anymore' philosophy.......
The guy who runs Tasman is a CSA pilot as im sure you are aware. Met him a couple of times in the office or the bar and seems like a nice enough chap. How his agency is run i couldnt comment as i dont actually know anybody who is signed up with him.
Hope that helps a little,
Cheers
