Something is still wrong with the current Ultrapeer implementation.

1. When you were connected to an ultrapeer and lost the connection, you are left without any connections. This happens to me every 15 minutes or so.

2. I know the horizon of an Ultrapeer is not accurately measurable for now, but in fact I get much fewer results when I am connected as Leaf.

3. Technical question: Why don't you insert additional tiers into the network. Wouldn't it be better to have level-1 ... level-N peers instead of just Ultrapeer or Leaf status. I mean the idea sould work even better with more than 2 levels.
