Replying to 50-50% freeride/racing boots?

alright so this a question mostly for people on here who race on their spare time. i race for my school so i can ski on the weekdays, but i ski a lot of park and everything else on the weekend and when i'm not racing. i need new boots and i'm looking for something stiff enough for racing (i raced with a 75 flex boot all season), but won't give me shinbang or rape my feet too bad in the park. so for people who race also- what boots do you use?

right now i'm thinking technica race 110, head S13s or the new salomon ghost boot, but any other suggestions would be great. if i get a list of good boots then i can go to some bootfitters, try them all on before next season and see which works best.

by the way i'm 6' 3'' and about 170 lbs if that makes any difference.
