I have a 7 gallon conical from which I can dump the yeast. When I do an 11 gallon batch with it and my bucket, I notice a difference between the beers. I do go back and forth as to which I like best though, but to me it is a discernible difference. I do remember thinking there was a difference the first time I didn't rack to secondary-but I was all too happy to get rid of all my carboys. I always dump/harvest in conical, and now wait till about day 10-11 to start dry hopping and a pretty nice "blanket" of hops covers the yeast cake in buckets after a few days. Unless you cold crash- won't you always have yeast in contact with hops, even after racking to a secondary?
