Fastlane or GPM or WHAT?!!!

Mike is not responding. I wonder why? Well, about the GPM prods. they're made of T6 aluminum and they are CNCed as well. Those who said that they're casted were right, but that was quite a few years. They now as they claim are using CNC technology. What do you think people? should I get some of them and see or should I wait for Mike to help me with Fastlane? I'm terribly confused.
