For single op SSB contesting, my suggestion is to use WinTest locally to generate the voice signal from a sound card and send it over the Internet using the remote rig mic connection. I do this using N1MM+, and plug my microphone into the same sound card, so that I can record everything locally. I found it much easier than using my K3mini/K3 combination. For CW, I use the Remote Rig Winkey emulator for my CW keyer, and connect my paddles to the Remote Rig paddle input. This way, the log remains at the Control site, and the operation is exactly the same as if you were sitting in front of the real radio. If you do RTTY Contesting, I demodulate the Rx audio at the Control site via a soundcard, generate my FSK signal via the Remote Rig box, and operate the contest as though I was sitting in front of the radio.
The only time I log remotely is when I'm doing a multi-op entry; then each op must access the remote computer via Teamviewer or the VPN and operate using the logging program keys. At the remote site is a full SO2R setup, but when operated remotely the only thing that is switched on is the linear.
