I did a lot of reading on Bruce Lee and Jeet Kun Do, and also have "The Tao of Jeet Kun Do". I've never studied formally, but have always been a believer in the art of "whatever works best". If you lock yourself into a particular style someone with adequate knowledge can eat you alive.

Also, in this day and age, in actual fights, outside of a dojo, people have a tendency to not play by the rules. Too many people carry weapons, and Lee said it best, "...against somebody with a weapon, you are at a disadvantage". Best defense is to not get into a fight, at all costs.
