After putting 80+ hours into Soul Silver when it first came out, I have come back to the game off and on. I already beat the 16 gym leaders, but right now I'm having a hell of a time training my team for a second go-around with the elite four. With my roster the way it is, I'm having problems getting past the first of the four. I've been trying to grind in mt. Silver, but it is taking forever. Is there a quicker solution that I am missing?
 
My team: 
Mawile 51 
Marowak 51 
Gardevoir 52 
Lugia 54 
Ampharos 57 
Typhlosion 57

Rebattling Gym Leaders is a good way to get EXP.

I think just fighting the elite 4--win or lose--is the best training method. You get a lot of money that way too.
