Possibly...I would also add that the weather, i.e. near freezing temperatures, may have added to the problem. It is not like a Pepin to split, again it is more than likely an isolated case.

I have had at least three Tats split on me and one simply explode. All were well rested and burned indoors at room temp.
Interestingly, and I'm not suggesting anything here, I have never encountered this problem with any sticks with DPG's own brand (blue, white, black labels).
It's to the point where I don't buy Tats anymore. Tried one Cabaiguan and truthfully...didn't love it. :2
Good review though, like the pics, love the dog. :ss
