Anyone have any thoughts on the reliability of the HAC system? How does it work? How is the 670 for reliability? Thanks for the advice.

The HAC is great when it works, when it goes out most people just bypass and rejet. The 670 motor is the most reliable motor ski-doo (or any other mfr. for that fact) has ever made.
