I will be giving this a try once it comes out to the fitters. I am very curious as to how it stacks up to the EF Subzero as to see if how much between single iterations. Although I am confident with the guys coming back raving about it ( without actually talking about it mind you which is a hell of a feat ), I can't NOT give it a run. It would have to big change for me to switch. Not to mention I might be playing a Speedzone by then.
