Those long par 4's at Sedgefield are all rather interesting. For the most part, the landing zones in the fairway are all down hill, so they don't play nearly as long as the yardage, but it's really the approach shots to each green that are challenging as they leave the player with a awkward feeling shot.
The tee shot on 11 will land on a downhill/sidehill slope, allowing for another 30-40 yards of roll. This will somewhat negate the extra length but does force the player to drive the ball down the right-hand side of the fairway to keep it in the short grass, but because you want to play into the green from the left everyone plays for the forward and left kick off of their drive. A miss left into the green is death, playing off of a draw lie its easy to aim out to the right for safety, but the bunker that sits short right of the green by about 20 yards helps keep you honest. When the green in firm this can be a hard approach to get close.
There is a small ridge that runs perpendicular across the fairway at 14, from the up tee everyone will land on the downslope and have their ball kick into the 160-170 range. From the very back tee, you'll need to carry the ball around 280-290 to take advantage of the slope. Over the ridge you're playing from a slightly downhill lie to an elevated green. the front right greenside bunker is a really great defense for any right hand pin.
18 for the members plays as a par 5, but with the fairway running down hill so much the tour pros can get an additional 50-60 yards of roll on their drives. The approach to that green is not easy as you are playing to an elevated pin from a steeply downhill lie. The two bunkers lurking short of the green add a level of fear into the approach if you don't elevate the shot well enough off of the downhill lie.
