Is that 1:50k window loads? or 1:50k clicks on the exit? 1:50k clicks would be a bit worse
Either way, it's the landing page. On dating go for the hard sale, fast.. screw the click, get them on the call to action, now!
And if you are loading dating tools (geoip crap) into a popup... that would be a problem. You need to load that page on your own box, your own geoip.. so the exit snaps open faster or doesn't slow down other pages loading.. and not having an iframe it won't pull the window over the main screen.
