Best Chassis, etc for a e-revo racer

I am building a brushless revo for racing
what is the better option (considering weight, strength and lowest cg)

1. A gorillamaxx e-revo carbon fiber chassis

Or

2. A vantage Carbon converted (has anyone converted that chassis yet?)
i'm thinking it could possibly have lower cg



thanks for any advice or help. I just wanna stomp the nitro guys, right now they are laughin at me and my brushless rc18t. So thats gonna stop
