Matt,
I haven't played the hole from the 150 yard tees. I did take a photo from there, but I didn't actually play that tee shot. You've often made the assertion that you have to play a hole to render a valid opinion, so I'm just commenting on what I actually know. No need feeding you more ammunition.
It does seem that there should be enough room from that tee. I think the angle is a bit friendlier as well. I just didn't play it from there.
You might reconsider your comment about the white tee shot just being a 7-9 iron. There are a LOT of golfers that woudl need more than a 7 iron to achieve a 150 yard carry, even downhill.
The staff at Wolf Creek did speak to our group, but it was only to caution us on cart rules, cart speeds, desert/ESA rules, and to ask us what set of tees we wanted to play from. Since the blues are listed at 6436 and the whites at 5820, we selected the blues. No one on the WC staff recommended that we play from the whites, and we wouldn't have listed if they had. No 7-15 handicaps are going to select a 5820 yard course. The staff also didn't suggest that we mix up tee shots on certain (or any) holes. While I agree that is an option, it seems that with the difficulty of WC the architect might have made whites somewhat more appealing (say maybe 6100 total).
Even though we KNEW the bailout area was there the second time around, it's still hard to perceive it's there.
The 9th is a tough tee shot, but from the blue tees you don't have to hit it any farther than from the tee on the 8th, but there is much more landing area. From the tees that you use, it might be a beast.
