Sidekicks #2 “Speedy”

Today's Sidekick is Speedy. Green Arrows right hand man/woman. I really like the first Speedy, then I found out that drugs missed him up, I wasn't reading GA at the time. I believe he has made a good recovery. What do you think about the Speedys over the years? Who do you think was the best? What do you think about what happen to them after GA?
