Does the L5 timeline utilize low or high chronology for Egyptian pharaohs?
While the low chronology is certainly more popular among secular archeologists, they are still many modern advocates of the high chronology. Some biblical archeologists believe that a high chronology provides a better fit with Biblical data concerning the Exodus. I believe this is the current position argued for by the Associates for Biblical Research.
Here is an excerpt from the Ryrie Study Bible showing high chronology:

Also, this is an interesting article on the possibility that Queen Hatchepsut was the Pharaoh's daughter who scooped Moses out of the water - again based on high chronology.
