It really depends on each individual how many frequency sources via remote they can tolerate.
I've had myself and a few others on 9 remotes at once without issue. I usually only ever had 2 that were focusing on killing modalities, while the rest were on healing modalities.
To have 9 killing would probably be very taxing on the detox pathways.
It would probably be best to add one at a time and make observations to see how well it is received before you decide to jump in and start running every remote you have at your disposal.
