I'm keen but the Old Road is a shitfight on the weekend. Loaded with police. Pie in the Sky is meh. Maybe a Windsor Start, Putty Rd, through Broke, Wollombi, Kulnurra, Somersby, F3. Or reverse of above. Kulnurra is a better coffee spot, and the roads are better (higher speed limits), if you don't mind sharing with sports bikes. There are other options if you want to go further south too; better Stagea roads and less traffic.
It really depends on how far you want to travel, and how long you have.
