Replying to How much heel lift is too much?

I have always had bad luck with ski boots.  My feet are so weird that even after going to good bootfitters and spending lots of money I have not been able to find the perfect boot. 

Nevertheless, the boots I have now are Dalbello Kryptons.  I have footbeds and molded intuition liners.  If I try, I can probably lift my heel about 3/4 cm.  Am I just overly paranoid about boot fit, or is it worth going to another bootfitter and spending $800 to try again?
