Hey Steve,
What did you do for legs in the beginning?
What do you do now?
At the very beginning (1999-2001) just squats, leg press, stiff leg deadlifts and sometimes lunges...because I didn't have the opportunity to did the other exercises with machines.
Then I still did squats and leg press in one workout (2002-2006) with as much weight as possible and then did 3-4 other exercises (at least two for hams).
But since 2006 I didn't use heavy weights with low reps anymore. My legs are a bit smaller now but once I start to use heavy weight again (as I did it last year) my legs gets bigger with 1-1.5 inch... But I don't need bigger legs. I need better legs. So now I'm doing at least 5 exercises per workout with 10-30 reps in each set.
