George,
I think those additions will be great in terms of bringing the intended architectural features back into play.
Don't tell TEPaul about the tees on # 7 and # 18 as his solution to the distance problem has been changing par from 5 to 4 on those holes, rather than moving the tees back.
This is why he has so much more to learn about GCA.
I think he liked replicating the approach shots on # 7 and # 11 at TOC at # 13 at NGLA.
Years ago I looked at the tee shot on # 12 from the left side of # 11 green.
I liked the diagonal hazard that the bunkers presented.
Not that different from the diagonal hazard on # 8.
I'll look at it again when I next visit.
The one thing that seems to make sense with that tee configuration on # 12 is the long catch bunker at the right flank of the fairway, well into the DZ near the downslope.
As it is now, there's no heroic carry required of any tee shot.
From the left of # 11, almost every tee shot would require the decision as to whether to be heroic and get a huge reward, or conservative and be left with a most difficult approach.
I might even play a ball from that general area, south of the road triangle and parallel with the front of the green, provided noone's coming up # 7. This is definitely a trial to be held after midnight
