How about Mesivta Atreres Shmuel of Durham, Connecticut, otherwise known as Waterbury.The Rebbeim there are by far the most caring and understanding Rebbeim that I have ever met. They respect each bochur for who he really is and in no way do they try to get you to fit into their mold, like some other Yeshivos do. They cater to every boy individually helping him access his unique talents to become a true eved Hashem.
Regarding learning, many of the boys are very serious in learning. They learn yoimam valaylah. Personally, the shtarkest guys i know are all from there.
And from a chilled perspective the guys are maaaad chilled. They go out to eat, they make kumzitzes they make fantastic crazy siyumin and concerts. They bowl they play basketball football etc. I think its a fantastic place.
