Not much difference if any at all. Most of the boots in the line are the same, the biggest difference as I understand it are the different liners and tongues. Just went to the Full Tilt clinic the other night and they make 8 different tongues that can be swapped out super easily. The Konflict and the Pro come with the highest end Full Tilt/Intuition liner, and the other models come with a downgraded Intuition liner. I thought the Power strap was also different on the higher end models, but it looked the same the other night so maybe they are running the same strap on all models this year. My Konflicts are in the mail right now so hopefully I can do a review in the next week or two.
