I keep forgetting to mention this:
Over on CRZ’s Wienerboard, poster HomerJFong has put up two really nice lucha related posts. There’s a list of his most favorite 10/11 matches of all time, and a review of a CMLL show, circa 9/13/97.
It’s really good, if you’re like me and want to get a little bit of an idea of what to start with with the older stuff you know little about. The first thread is closed (time), but the second one should still be open for comments.
