Short Cut Broken Hill to Berri

Hi All,

I am driving my boss from Broken Hill to Berri next week in the work Crummydore. I don't want to follow the Silver City Highway all the way to Mildura then head West. From the Natmap Rasters, an option would be to take the Pine Camp - Springwood Road then pick up the Main Wentworth Road and come in through the back of Renmark cutting out over 100km, but adding about 130km of dirt roads. Has anyone travelled these roads and knows what they are like?

Thanks

Pete
