This is a topic for debate. Many brewers never rack their beer to a secondary, no matter the style. Just as many do. I always rack my beer to a secondary unless I'm brewing a Hefeweizen. For me, I do it mainly so I can feel connected to my beer. Leaving it alone for several weeks is just too hard for me.
