True Lefty, 900G probably is using a variant of M80 on their equipment, but I would like to see them use the cores from the Action series. That combo really worked well for me and all 3 of the Action balls I have really gives me a complete arsenal except on bone dry.
I also agree with kidlost2000, since Ebonite bought out C300 & Track, I view the balls under those labels as not being the same product, just variations on Ebonite. I just haven't found that I match up with the Ebonite gear I have thrown.
