Suited connectors are my favorite hand by a long way - anything above 4-5 suited really. Thing is that you can win a huge pot when some donkey spikes a TP type hand, and they can be great for bluffing the flop too - since you will have outs many times.
I do not usually raise with them pre-flop (usually playing full-ring) since this is the kind oh hand which actually benefit from more players in the pot. If someone has the math which shows profit expectations as you increase the number of players then give me a shout.
There are plenty of ways to win a pot with the suited connectors. Below is the basic math for flopping a good hand with them:
Two pair: 2%
Full house: 0.09%
-------Total: 5.6% (1 in 18 times, 17:1)
Remember this is flop only and does not even account for those times you flop a strong draw or a combo of somethings like a pair + a draw.
