If your looking for a school in Manhattan that has a good mix, check out NY Combat Sambo. Yeah they are a Sambo school but they are definitely progressive. Think of it more as a grappling school. Good take downs, Stephen Koepfer shows great stuff from the Sambo side including throws and leg locks and Tyga Maclin is an awesome wrestling coach. One of the only schools I know of that actually have a dedicated wrestling class. They have striking classes as well, never attended but from what I hear they are great too.
Also the biggest thing I like about the school is that EVERYONE IS COOL! I've been to a lot of schools and let me tell you, a lot of schools have the team "douche bags" as I call it with a group of guys who are always assholes. Not this school. GREAT atmosphere.
If your ever in Queens, you can check out queens-mma.com (website is kind of shitty).
