Just remember to take it easy and don't push it just to make a dead line. To many accidents because of that. Plenty of the places you have listed maybe graded the week before you get there or not graded for a Month before hand and this will dictate your travel times. The Oonadatta (can is usually in god nic but sh1t to Dailhousie if your going there, stuff like that. The track to Hallagen Bay (Lake Eyre South) is also rubbish due to the rock and it is a hard trip for a day - well worth it but please take care
