I am all-glass in secondary because it will not leach over long exposure (yeah, yeah, I know what the plastic ones claim), you can use vacuum, it cleans easier and it is not flimsy. A glass carboy will not tip over when siphoning out liquid, after it reaches a certain level. Plastic can do that.
I use Brew Haulers on the carboys. An excellent investment, easily transferable, and I found them very cheap.
A year or more ago, I saw some pix of a Midwest Supplies guy who cut his arm up when a carboy he was brewing with broke.
I looked at his eyes in the pic, not his wounds.
And so I'll say it again: Never EVER drink when you are making wine, brewing or bottling. If you must bench test, taste and spit it out. Drink afterward, when you can celebrate safely completing what is truly an industrial process.
