Eric, as MBaggese said a few posts up, Tour Legends are on Champ Greens with Low Winds, with a mixture of new/old pins. Interested to hear that Legends are playing in Moderate winds, so your/their set-up is slightly harder.
Well done to TaulAcePaul with his 58. Can't say I'm suprised though that someone has gone so low. I've only played it a couple of times and the scores are there by staying out of trouble, by hitting the fairways (Kia is arguably the easiest driving course on the game) and then making GIR. As always then putting becomes of paramount importance. As you said putting on Kiawah greens (especially on Champ speed) is quite a lot trickier than at BPB. Course management of course is far more important than usual and I'm sure this comes into play far more on courses like Olympic and Oakmont.
This is all from rather limited experience I'll admit, but personally I think Uneven Lies is a good concept for experienced players. It adds an extra dimension to the game and forces you to think more around the course. I do worry if it might be too complicated for new players to take it all in - some might embrace the additional complexity/potential realism, but I feel more will be put off by too steep a learning curve.
I still feel Uneven Lies need to be tamed down a bit more (especially on shorter shots from Wedge down) - not to make it easier, but I feel some courses (BPB/Kia) will play considerably easier than others (Oak/Oly), which doesn't seem quite right to me (maybe I'm off-base here).
It's also quite a strange concept to feel you need to really attack and cash-in on the Par 3's, which traditionally tend to be hardest holes. I had a quick look at the 2012 PGA Championship Stats:
http://www.pga.com/pgachampionship/scoring/course_stats
Score averages over the entire Tournament came in at:
Par 3's - 3.227
Par 4's - 4.120
Par 5's - 4.920
That's the order of difficulty I'd expect to see and I'm sure the same order of the majority of WGT players who have been playing a while. Of course the counter-arguement is that those numbers are way higher than the scores we would see on Kiawah with Even Lies by decent WGT players, and Uneven Lies helps to bring the numbers closer to those of the real Pro's.
Slightly off tangent here, and I've been saying this for a while (since the Burners and Callies came in) but I'd also like to see equipment downgraded across the board / meter sped up (I know this won't happen - imagine the moaning!) to bring scoring up for everyone.
Didn't mean to write so much there... better get back to work!
