....also WLP 001 is a very easy to use yeast, not at all temperamental. Great beginners yeast and again very forgiving of mistakes.
+1. That yeast is a beast. Just remember that every yeast does have it's own behavior. People have been recommending starters not because it's a one size fits all approach, but because eventually you'll hit a style of beer that you absolutely have to pitch more than 100 billion cells for a 5 gallon batch to get the optimal flavor profile and attenuation. More often than not, it's better to err on the side of a starter. Of course, overpitching can also give you sub-optimal fermentation, but by commercial standards homebrewers almost always start by underpitching.
