Pede Question

I've got some good packs. I can get anything I need at a good price. battlepack.com is just 15 minutes away from my house. Great prices and a easy guy to deal with. I've been running gp3300's with a 15 turn motor. He built a 3800 for me and its a whole new truck. But I want to go faster. From what I see on this forum there are several ways to go. I just don't want to spend a bunch of money and not be happy with the setup. Can't wait to get it done though. I've got an emaxx and a savage that would I'm thinking about going brushless on too.
