I think that the Equinox course, despite the Rees-ification, still embodies the "Travis-feel" that was intended. There are several fun aspects of the course that would predate Rees, such as the par five played over the road (the road is in a small valley 20 ft below the fairway), the "crater hole," where the green is on a hill that appears to have half washed away, and the short little par 3 that follows it.
I was initially surprised at the similarities in routing, with the opening holes spread out on the gently sloping hillside below the clubhouse, the 90-degree perpendicular turn both of the front nines, a few hills around the edges...etc.., but they are on adjacent land, so its really no surprise they are similar. Ekwanok is no doubt a more pure test of more pure Travis, but Equinox is a fun layout as well.
