i have ridden that trail twice since all the floods and big rains.
i think you will be on that trail longer than 12 hours IF
you have anyone that is not locked front and rear and winchless.
The floods have made some sections extremely difficult with a high white knuckle factor. The skeg field is mostly dry so that should be ok but there are some brutal uphills. Also, the 'posing' section that has the erosion where you are forced to deke between the trees to get around it will see everyone on a winch as the erosion is big and steep.
After you cross the river at the 4 corners, you will soon be in for one incredibly tough climb. Very eroded and off camber. After that it is smooth sailing from the bent tree and beyond.
Maybe i have been on a bike too much but i think that any jeep not locked and winched is not going down that trail. There is one mud section that is tough now as well.
Having said all this i think it is now an even better trail
