I have not hunted with CK yet but lots of TG members have. My current employer has me busy out of country for the next year or so, but CK's operation is on the top of my list when I get back. Just from what I have read he has a first rate operation. Some of his better known hunts are the Texas Sweat, and his hunts that are combined with bowyers like 7th Age meets Dyrad bows, Striker bows, and others.
Shoot him an email I am sure he can help you with the hunt you would like. Also he does bowfishing and frog hunts which from the TG video look like a blast.
You can also run a post asking member about Curtis Keller and 7th Age. I am sure you will get instant feedback from members.
Hope this helps,
Chris
