BLAH, BLAH, BLAH, A lot of people talk smack about each of these products, I think if you wnat a little more from your bike they are good, yes the pump works, yes the powernow works. The best bang for your buck, well that depends on your riding style. MX I would say get both, I run both and have "0" bogging problems and smooth take offs. But it all about what you want as the final result. they are both about the same price.
