what's recommended max for 404 popups & exits trains?
 

I got my 404 page, but I thought, well, what if surfer dont like what I offer, so I thought about adding popups & exit consoles. what's the recommended maximum I should use- 3, 4 or more?
I know it will piss the surfer off if I had say 404 with a popup & an exit console on both of those & an exit on every exit getting him stuck in a train of exits & popups?

Or should I just have the single 404 with no exits
