The ten foot four weight Marksman is much more responsive than the Greys. The flex point of the rod is higher up near the tip. Where as the Greys is closer to the middle. Now if were were Comparing the Greys in the same configuration, the actions are quite similar, the main difference would be that the Hardy Marksman is a slight bit more responsive, which means that it dampens more quickly when flexed. This is why I think it keeps the hooks in the fish so well. There is no wiggle.
