My T500 gives me an acceptable product with a single run and no filtering. The magic ingredient being time. Long cool ferments, wash clear enough to not need conditioner. Pouring the wash into the still is enough degassing after 5 or 6 weeks in the fermenter. Very slow low temp run, ~42'C. Although I've found that about 30 minutes into collecting hearts I can increase the temp to ~52'C with no loss in quality.
I've no doubt that those with sensitive taste and smell could find fault with my vod but everyone that tastes my stuff rates it better than store bought. Then again, I don't mix with people that pay over £30 for a bottle of vod.
wrt leaving the still unattended, it is a question of degree. If you do the same thing every time, it becomes routine. If you are the type to never be at home, then buy your booze in the pub.

If you're home for the day, might as well run the still. Total invested time for a run for me is less than an hour. That includes making up a new wash, which happens while the T500 is warming up.
