I find it more pleasing personally but you have to be your own judge.
I would still be wary of shooting it above 250asa, you can buy back a little and avoid flickering street lights by going to a 216 shutter, but it still wants a lot of light. If you plan on crushing your blacks anyway, 320asa can be acceptable, but be careful how much you dig!

The improvements in Build 20 for low light are huge, especially the improvement in blue channel noise.
The maximum acceptable ISO is really dependent on your project - I am now shooting some Canadian football playoffs at 100fps in 2K, for HD finish. With some finesse in the blacks by the colourist, 800 looks really good, 1000 - 1250 still cuts quite acceptably with HD footage from the live truck. The extra speed helps me narrow the shutter as much as I can to keep motion crisp. I might even try 2000 for a few shots to see what happens!
Last year I did a similar shoot, and 400 looked good, but 640 was really on the edge of acceptable, with noticeable blue noise.
I would absolutely test to determine where the threshold of "acceptability" is for your particular project - you can push an HD television project much further than a feature film! Regardless, Build 20 will definitely be noticeably better than 17.

I recommend 1/60th to be absolutely safe. I did some testing and 216 isn't actually that safe if you're dealing with magnetic ballasts on any kind of light.
I rate RED at 160, and it works for me--but I find I still have to overfill and pull down the blacks to stay absolutely clean. The blue-speckled noise is gone but otherwise it's still fairly noisy if you underexpose it and try to pull up the shadows later. I give it a beefy exposure using 5600k light whenever possible.
It does look better under tungsten starting with build 20. A lot better.
But--I don't at all consider it a low light camera. George, I'd love to see some of your footage as, frankly, I'm a bit sceptical--or I don't get access to the same noise reduction options you do.

The posts you have included are very much out of date, as RED One at Build 30 is a different camera & RED One M-X is a dream in low light, and, while some disagree, I believe it is native @ 800 ASA & I shoot everything at that EI with fabulous results. Not so great at 2000 ASA - crawling blacks, but still gradeable.
However, there is virtually no difference in the mid tones between 800 & 2000, so no advantage in changing EI from its native 800.
