Sufficient yeast??

[niker0101]

Making my first AG 10 gallon batch (finished product) and was curious if one Wyeast 1056 smackpack will be sufficient yeast for the yeild I am targeting? I am making an APA with 15lbs 2row pale and 2 lbs caramel 40. Wish me luck....

Even for a 5-gallon batch, a starter's a good idea....
