Default Carboy Size: Single Vessel Fermentation

So as some have suggested on this forum, I do my entire fermentation in one carboy. No secondary. My question is, for this style brewing, what is the ideal size carboy?

the 6 and 1/2 gallon ones work good for that. course they're really heavy. i used to use em. but switched back to a 7g bucket.

Typically, you'll want to have an additional 1-2G of head space on your vessel, for the krausen. If you used a 5G vessel for 5G batches, you'd lose volume every time to blowoff.

I choose what carboy I'll use based on what beer I'm brewing:

A big beer? Better use a big carboy.
A small beer? Better just shoot for 6 gallons and use a big carboy.

Not to knock your product, but I just can't justify SS being worth ten times more than a bucket. Not to mention that because of the dimensions the temp difference from the sides of the cavern to the center, would be bigger than in a bucket.

I could see it being nice for aging wine.

Although It would definitely be more appealing if you had a lid with a cooling system. Maybe not a refrigerant filled helix with a pump and condenser, but even a spot for an ice pack to fit down in the center of the wort would be a significant advantage to homebrewers.

I use 6.5 gallon carboys and have only had the kreusen invade the blowoff tube once on 12 batches. Too much headspace in this to use it as a secondary IMO.
