Correct BS for pair of 9's vs. Ace in SD, H17 game??

I'm heading to Reno Thursday and am planning on playing the abundant SD, H17 games. I'm in the process of memorizing the proper basic strategy, which is somewhat different than the DD, S17 strategy that I'm used to using in Indiana. I've noticed just 1 difference in the BS charts posted on 2 very reputable websites. Wizardofodds.com says to always split 9's vs. Ace, but blackjackinfo.com says split only if DAS is allowed (which it is not in Reno SD games). Does anybody know which one is correct?
