I have nothing against those who think there is a benefit to racking to secondary, but like Marshall says : don't claim that it somehow improves the beer...I use kegs as bright tanks, but that is for clarifying at lager temps when I am simultaneously carbonating and then later transferring keg to keg with a spunding valve for a clean transport (i.e., settling out all yeast so that the transported beer isn't stirring up yeast that settled out). Long term sours, fruit beers, heavily dry hopped, etc.. will see a secondary, but if I can avoid a secondary, I do. Not that anyone else has to follow my practice - I just do what works for me after trying it out for myself. (Per a noted Noti-ite.)
I always take that position, except with a neighbor who is convinced that Star San is dangerous, so he only uses Iodophor!!
