Have a question about warranty on a 910 D3.  I have one that had a dent on the heel, which I knew wouldn't be warrantied due to the location of the dent and the fact that the dent is there because of the fact I put it back into the bag without  putting the headcover on after hitting a bad drive and it banging against an iron in the bag.  I continued to use it because of how the damage was caused (taught me a lesson too that no matter how bad a drive is, still take care of your stuff).  So I thought nothing of using it and it was working fine. Until it split along the medallion on the sole.  It's split from the heel side of the medallion almost all the way to the toe.  Is that something that could be covered under warranty or is it trash since it has a dent in the heel too?
