That is the important part, if you have worked hard on it and feel that it is a good print, then good on you. I would not be as concerned as I think you are. I will point out one other thing, if you are sending out 5X7, if it is framed, it will probably be a desktop frame which mounting might cause problems with, since the easel is attached to the backing board and a mount board might be too thick. My personal opinion is that if I am shipping a print, then just do that. People will always want to choose their own framing materials, just a fact of life. If you were hanging it in a exhibition, then I would say to mount it,frame it, what have you.
