CA Final coaching in Mumbai for Nov 11

Hi all, I am going to appear in CA Final group 1 in Nov 11 and group 2 in may 12. I live in Goregaon West, Mumbai and looking for CA final coaching classes. Few ppl have told me abt Vatsa Tutorials, as good one because of limited batch size of 25 and good results but it is relatively new class. whereas in J K Shah seems to be oldest one, but with hundreds of students, one cant expect that his doubts will be solved at all. I am slightl confused. please advise, which one to join
