Simpson Route Planning

Finally doing the Simpson from west to east has come to the top of the list for later this year. I have many maps and have read what is to be found on this site and a few others. My problem is that there are so many combinations of the various roads that I am finding it hard to decide.

We are not into finding hard tracks just for the sake of saying we have done them but am happy to tackle something challenging if there is need.

We want to see the range of country, the bird, animal and plant life that goes to make the Simpson what it is. We will be taking the Troopy on this trip (no towing) which is well setup for remote travel and we are experienced.

So taking into account that the northern section is likely to still have problems what would people suggest?

My current thought is:
Mt Dare - French Line - Waa Line - Colson Tk sth to Rig Rd - K1 Line nth to Qaa - Birdsville
