Suited connectors are great because they are so easy to get away from. If you make middle pair you can easily dump it but they can produce some very strong draws (which play great in multiway pots common at lower limits). It is not surprising that Big suited broadways oftentimes play better than QQ and lower PP because you can too easily get attached to these. Big suited cards play awesome multiway which is almost always the situation in the loose games at lower limits. With too many players seeing a flop after a raise, Big suited and connecting cards play awesome and pocket pairs get harder to play. Say you have AA and the flop is K 9 2 rainbow w/ four people in the pot you could either be really far ahead or really far behind but if you have KQ of hearts and the flop is JT2 and the JT is hearts you are guaranteed to be the advantage over anyone in the pot...
