@dlehenky and everyone!
The aforementioned xeronet Rocket torrc is now available via tornull.org - do give it a try and experience for yourself just how fast Tor can be if ididedittheconfg 
For anyone looking to run Zcash on Tor the basic configuration instructions and addnode=.onion’s can be found in my post linked above. I’m working on a more detailed set-up guide.
Also, a large block of ‘trusted’ US based Tor exit nodes were seemingly established after the Zcash ports were added to the Tor Reduced Exit Policy. They can all be located via the Tor Atlas as ‘Quintex’. They would make good ExitNodes additions for anyone running Zcash on Tor. Although remember that torrc characters (per line) are limited to 4096 for ExitNodes etc., (hint: listing servers via IP address uses less characters) …
I’m working towards setting up an optimized Tor enabled P2Pool for Zcash.
