Your absolutely correct, a machine went down in the recent stats (then an orphan, then 5 hours for 3 coins), sometimes you go on a tear, some time your mining for hours until you get an LTC. The one down side to Titans, is they don't "spin like a top" necessarily, but they’re certainly the best available.

crazy short term gains working with altcoins
We haven't had much luck mining altcoins with these machines.
I typically had between 0.2% and 0.3% rejected shares, and the pool was running at ~70Gh/s (I was ~2.1GH/s of this) the whole time I was there.
Typically We have between 0%-.4%, I would estimate ~0.15% mean.
Anywho, back on topic. The machines are worth more than $3K shipped as a farm with ample PSU's and custom FW. I'll keep this open for another week or so and when LTC goes above $5 and stays consistent at .012-.016 BTC, we'll reassess for the new year.
Thanks to everyone for the civil discourse, it's quite nice!
