This challenge will come down, imo, to how the daws choose to run it. They will all do it together. Remember in some of the water challenges with Ozzy, he did multiple legs in leiu of some other slower folks....if they are allowed to do that in this challenge, the Ome's may have a chance.

Best case scenarios:

1. Crow bar leg to open chest and get shovel: Zap: David or girl, Ome: Andrea?
2. Grab shovel, dig up ax: Zap: Julie, Ome: Grant
3. Ax chop to release the saws: Zap: Rooster, Ome: Rob
4. Saw down the wall to get the planks for the ramp....IMO, this is the leg that will win or lose the challenge. We see in Blind Freddy's vidcaps that the Purple team was way ahead of the Orange team, yet the Orange team SMOKED the purple team at the sawing, pulled ahead and easily won the challenge. So, if Rob participates here with Phillip or Grant, I think they'd have a chance....if a girl does this with Phillip, they are doomed. Most likely to do this challenge: Zap: Mike/Steve Ome: Phillip? Grant? Rob? Andrea? Most likely to succeed at this: Grant/Rob?
5. Place the planks: This is not a real puzzle, more like a matching challenge....Ome: all of the girls and Phillip - Actually, we see the same guy that did the sawing placing a plank, so I think they all can place a plank, so all from both tribes
6. Hammer: Zap: Rooster, Ome: Rob

So, there is a chance that the Ome's could win....it will depend on whether Rob and Grant are "allowed" to be on fire here...of course Rooster could be "on fire" as well...No doubt about it though, at this stage the Zaps should be heavily favored.
