Opening Database For Non-Masters

Simple fact is, im not that good and what works for a master has no bearing on me. However, i would be curious as to what opening are successful against Class A,B,C,D players respectively. Also, would love to know which ones do better under different time controls. Thoughts?

It would be possible to play around with a database of games and come up with winning percentages of different openings at different rating levels. 

   I remember reading a thread on chesspub a while back where someone did that for a specific opening.  I can't remember what was said though. 

Have you tried www.365chess.com, Matt? The free database is for young people and average players games with the odd high-rated game thrown in.
