"The "look" of the tees is as if they have been there 50 years. They are harmonious with the old tees."
Don't Bogart that joint, Mike. Pass it over to me. Are you serious?!
Some of the tee work is excellent, but not all of it is as you categorize. The laser lines and levels demonstrate excellent technical skills but are a bit out of place on a classic course, don't you think? It might have been better to simulate a bit of old-style in the construction to make them really look like they've been there for ages.
There is nothing at all natural about the look of the new tees on 5 and 17 (an improvement would be to have the tee on grade to the left along the line of play) nor is there any harmony at all with the existing tees; they are completely distinct in look and position. I find it curious that you think otherwise.
On the other hand, the new tees on 2 (although oriented at a wrong angle), 6 and 16 are excellent. The 18th is at the base of a large tree on the north side at that. Not only should the hole remain a par 4 but the par 5 back tee is in a position that will prove difficult to maintain turf.
Now, see if you can get the club to put a back tee on holes 7 (+15), 8 (+30), 9 (+25), 10 (+15 as on a Flynn plan), 11 (+25), 12 (+25 tied into 9 tee) and 14 (+20; I'd take the sod off the new 18th tee and put it right above the current tee behind the path). Then get them to get rid of all the internal evergreens. A tall task, but you're up to it!
By the way, the work at LuLu was a great effort from design to construction. Way to go Ron, Jim, and the boys from Traverse City!
