It's cheap and easy to run a second camera to catch the action from a different angle.It's nice to know that you are open to ideas Fran.
It may be my AADD, but seems like some producers do that same thing over and over with different models. I myself like variety and it seems that each of us want something a bit different so it makes sense to me that a producer should provide a variety in order to sell more, especially since a lot of video is sold in smaller clips these days.
I hope that you find some more success and decide not to close shop.
