Thanks for your question Alex. We actually just finished a seminar series called the Days of Thunder which talked about your exact question. In our video demonstration, we showed that the X Factor ACE is approximately 4-5 boards more aggressive than the original X Factor. The ACE still maintains a strong entry angle, as does the original X Factor, but the ACE will create more friction than the X Factor.
The ACE should allow you to get a little deeper with your feet and still maintain the same strong backend reaction. FYI....Jeff Carter just won the SW regional in Ft. Smith, AR with the new ACE...
Good luck!
