I would also consider unit 103. The Black forest area in unit 104 / 105 does hold some good bucks though. I know 142 isn't a slam dunk due to the military base - there's no guarantee when you'll gain access to the public ground. Just my $.02 - good luck, let me know if I can be of any other help.
That is a lot of points! I have a friend who is sitting on 14 and has been considering Kiowa Creek also. I jumped on the partial point burn in 2006 and got two hunts out of my pot and had great hunts on both trips.
So what did you end up doing?
I hope you checked out the bucks that they take off from Kiowa and talked to them first either way. http://www.huntkiowacreek.com/index.html
Whether you went with that hunt or another, I'd be very interested in hearing how it goes and whether it was worth the points to help determine where to burn my friends accumulation.
