My thoughts on the new placements:
6- Eh, it was ok, but not as good as the later new placements. The little trees guarding the pin make the green an interesting challenge and are the best part of the hole because the drive is not really that difficult to get up there. A good hole and definitely harder than, say, the short placement on that hole.
11- This was a pretty sweet hole. In my opinion the raised basket is something that KC could use a lot more of. I do wish that there were another placement on this hole drilled into the boulder shorter of the new one... that would be a pucker factor. One suggestion for the new placement would be to clear out some of the brush and whatnot around behind the pin so that if you missed your putt you could not be saved by those things.
12- I liked this one a lot. It is a very two-able hole, but also a very four-able hole if you mess up your drive, which makes it a good hole. Only knock on this hole would be that towards the end it is sort of a poke and hope hole, though that is a really nit-picky criticism.
16- This one is ok... though I think the two is very hard and the four decently rare, at least in doubles play (for the four I mean). For my money I think I like the older long placement better because it really brings the two in and allows for the diversification of scores between two and three instead of the longer one which becomes largely a lot of threes and maybe a few twos.
Good Work on DU, it is looking AWESOME, especially with the cleaned up dead trees, sweet refurbished tee boxes and shiny new baskets and placements. Keep it up!
