Good luck man, conversation was the biggest issue I had with OLD, there was only one person I met OLD that I had a good conversation with. It seemed the better looking they were, the worse the conversation was, and no I'm not saying that "hot" woman can't converse. I think it's probably a by-product of how many messages they get that they feel like they can't take the time to really get to know one person. Or maybe they just couldn't take the time to get to know me, who knows.
I will say that I preferred POF to most of the other sites I tried. It seemed like most of the people were on all the sites, but I liked the functionality of that site the best. But I guess it depends on what you're looking for, Tinder is based solely on looks (i.e. hookup app), so probably the best chance to find the physical affection the fastest.
There is also an app called coffee meets bagel, that one has a lot of built in delays, only showing a few people per day, so I felt like it would give a better chance of getting to know someone without having too many options at once.
