Bottom line is, take ALL of the classes you want or hear about; if you can afford them or feel they will benefit you. What is problematic is YOU deciding what YOUR life is worth based on word of mouth. Now think about that for a minute. "I will not go to Front Sight, because someone told me they suck!" Or, "F Vanilla Gorilla and his class, because someone said he sucked!"
Amen, am not high speed low drag. Take classes when I can.
