Re: [tor-relays] Using your own Relay as Entry Node

I'd say it's a tradeoff. You may have more trust of your own entry guard, but you're losing the benefits of guard rotation and possibly making it easier for de-anonymizing attacks to occur. From the man page: "We recommend you do not use these — they are intended for testing and may disappear in future versions. You get the best security that Tor can provide when you leave the route selection to Tor; overriding the entry / exit nodes can mess up your anonymity in ways we don't understand."
