glover is kind of nuts and the whole feed in from the running classes to the club is just bad. gny is not a great idea.
manhattan track club is a nice group but quite competitive - be prepared to run your ass off in group sessions because most of their guys broke 30:00 for the 10000 in college.
you might also look at Urban Athletics who do their speed work on the e. 6th street track. CPTC is fine with nice people. Warren street has some decent runners but not too many young people any more. Harriers and flyers are mostly slower than you. there are also a lot of smaller clubs around. nyrrc has a pretty comprehensive list.
