I seem to use both SAE and Metric equally. In fact, when I hear (read) about guys who don't own or use certain tools (metric or SAE) it seems weird to me. Whenever I buy tools, it's ALWAYS in pairs. For example if I buy a socket or wrench set I ALWAYS buy 2 sets, one in SAE, and one in metric. I would never only buy one or the other.... its always both.
