Replying to Old Jesters

In the past three years I've had the Jesters on my park skis and they've functioned well however, the magnesium track on the heel piece has worn down super thin where it slides on the plastic base plate so that its not safe to use them anymore. This is the second pair this has happened to (pictures coming soon). I do weigh about 180 lbs and ski really hard and do a lot of nose butters. But still this is a pretty serious design flaw in my opinion. I took a look at the new jesters and they seem to have changed that part of the heel piece. These jesters are like 2009-2010 i believe and so were my old ones so i dont know if they will be warrantee able. Let me know what you think.
