Winter, the Mexican blocks we found were always thicker than the US blocks, and it was about 50/50 on the Canadian blocks. The Mexican blocks were over .200 thick at standard bore, so at .060 over you still were at around .170 thick. And occasionally, we had several end up being over .200 thick after a .060 overbore because they were really thick. Every once in a while a thick US block would come along, but they were few and far between.
