Haig to Cocklebiddy

Are you sure you don't mean Rawlinna to Cocklebiddy ? Did that in April.

Regards

Thanks everyone for taking the trouble to provide some feedback on this query. Much appreciated.

The Cocklebiddy to Rawlinna Rd doesn’t offer a lot of shade.

Just answered my own question, for anyone interested.
The trans line from Kalgoorie to Haig is in good condition, and a pretty easy run with the usual caveats about driving to the conditions. Interesting sights along the way, and good opportunities to camp - we chose Zanthus and Haig, but you are spoiled for choice and there is plenty of rail traffic to keep you interested.
The drop down from Haig to the Eyre Highway near Cocklebiddy is another story - quite a challenge for vehicle and driver (not to mention my passenger, who also had to open and close innumerable gates!!)
It is basically rock all the way, and if you want to avoid damage most of the time is spent checking wheel placement rather than admiring the (extremely flat) view.
It took us six hours to cover just under 120 km, and when we aired up back on the highway I was congratulating myself on getting through unscathed. Then, another 20 km on the bitumen and one of the camper tyres gave me a stern message.
