Replying to Full Tilt Booters

So, I went into my shop today because I've been having some problems with my boots lately.  I've had them for four years with no problems, but this year they are absolutely killing my feet.  Talked to the boot fitter and he said he would try to help out, but when he took my liner out of my boot he said it was basically shot to shit, and the boot board was also all torqued out of shape, and I could probably use a new pair of boots.  He measured me up and fit me with some Booters, Agent 80s, and Rossi SAS, out of which I can't really decide between the Booter and the Agent.  I have Agents now, so I know I like them, but the Booters felt amazing on my feet when I tried them on.  I'm going back on Thursday to try them on again and make a decision.

Does anybody have any experience with the Booter that could give me some insight? How they perform in/out of the park, durability, 3 buckles vs 4 buckles, etc?
