Hopping through my own Tor nodes could be a bit counter-productive, as it would make attribution of my circuit quite a bit easier.
I use an extended hop relay with hand-selected nodes, which allows me to use five hops instead of the standard three, and hand-select fast relays that are in nations which are unlikely to share information readily. There's a few more tricks I use to counter e.g. stream watermarking, but at a certain point you reach diminishing returns, as the browser is only so secure.
If I was running a drug cartel, it'd be appropriate COMSEC, but for me its really more of an experiment than anything else.
