So it seems like the consensus here is 'no secondary'.
Yup.
I secondary to dry hop now. I'm planning to even change that up by dry hopping late in the primary and dry hopping again in the serving keg when I do an IPA soon. Me likes hops aroma.
...
If this is the case, why do some people use secondary? Are there any benefits?
As I see it, if you want to bulk age your beer for a loooooong long time, e.g. lagering for 6-8 weeks for a Doppelbock, or a long bulk aging for a RIS/Barleywine/etc, a secondary is probably necessary to get off the primary cake after 4-6 weeks, since the yeast are stressed from the higher alcohol content and may autolyze before the beer is fully conditioned. Even then, if you keg, you can condition in the keg, and remove most the sediment by pulling a pint off with a cobra tap and discarding it every month or so (assuming your dip tube reaches to the bottom), so there is never a need to secondary in that case. I'm planning to do just that for my lagers... they'll sit in the kegerator right next to the serving kegs.
The footnote to this is what Revvy keeps pushing: give your beers time to condition in the bottle/keg. If you drink green beer, guess what, it will be clearer if you secondary, since more yeast will drop out.
I'm patient, condition for at least six weeks before drinking, and haven't noticed a difference since I stopped using a secondary. The first couple of pints have sediment out of the keg, and after that, it's clear.
Now that I know secondary isn't necessary (and more so, that some of you have had better experiences w/ out secondary), can I use a standard better bottle or glass carboy for primary (provided I keep the light out)?
I love 6 gallon better bottles as primaries. I switched 4 batches ago and haven't looked back.
