Actually I was pretty good with the opening lines on those sites. I'd say 90% of the time I got the person I messaged to look at my profile, but not a very high percentage responded. I did like the way you could filter through types of women though. That was the main reason I tried them so long thinking I could save time and money. I might try the free ones again sometime soon, but not paying for that crap again; wasted hundreds on those sites.
