Hi shanan,
They are unsinkable I have one the same as yours which was once dean mercer's as it has his name inside and they just keep going. All our new burton skis are all slsa compliant with the quick release etc are the only changes made.
It's good to hear that you race it and that it turns heads. If you are after a new one they are back and still just as fast if not faster.
Regards
Cy
