Big fan of the unlimited 3x night add ons.
For only $5.00*, you can have unlimited downloading during the hours of 1am - 7am for 3 nights!
You can do this just once, or repeat this process as many times as you want over the month. Please allow 15 minutes for the rate limit to be removed at 1am and reapplied at 7am.
However, the problem is that utorrent only lets you schedule in 1 hr blocks, so if i schedule from 1am -> 7am I often get stung by the 15 minute changeover and end up using a lot of my monthly data.
I think that if you change this time period, people will still only attempt to use torrents over the 1 -> 7 am so I don't think you will see any extra traffic in the 12->1am and 7->8am time periods.
