I'm still getting some PM's about getting my optimized miner.  For the moment, I advise people not to unless you really want to mine hard for the next few hours.  Given jh00's experience optimizing the xpm miner, and given the chat on ypool, people should assume that until proven otherwise, the ypool miner will blow everything else out of the water for a while.  Wait until it's released and we have a comparison before wasting donations on mine.
