So following Destiny's ZvZ build in g123:

I tried it out on ladder. The first game I tried it, I lost because of early mass roach push. It's okay, didn't really know what I was doing. I still feel I'm not sure how to do it because Destiny says roach play like this will get owned by it.

Second game I did it, it was absolutely awesome! I know I outclassed the opponent, and could've probably beaten him anyways (he was gold, not really good anyways), it was a lot of fun! ZvZ, imo, has always been a fun match-up, but damn this game was amazing! Here's the replay, dunno if its really worth watching but if you haven't heard of it, it's pretty cool. It's a long game but in no point was he ever in the lead.
