It is a very, very ,very bad idea to have Cam 5 be the free cam. That is the BEST view of the couch. If they have sex there, which they will, all of the subscribers are going to watch from that cam and guess what, NO MONEY!!
The free cam should always be the worst possible view so that if action happens, the likelihood of the subcriber viewing from the free cam is minimized.
The free cam should be the the one on top not the one on the bottom. They will lose a lot of money with this set up.
