I don't know -- i have some experience with the use of big blades in tactical scenarios -- i would bet that i could get across a room or down a hall with a big chopper as fast as i could effectively draw and aim a pistol; compared to the shottie, the blade could be a little slower, but no danger of overpenetration (well, maybe with GF's new flying Nuke, there would be), and level of force can be pecisely modulated through use of different target zones -- i would be comfortable clearing a structure with a big blade in about any position but point (which is ironic- inside joke). I think edged weapos are about the most underrated threat in modern CQC... oops typing too much -- i must not have enough drinks in my hands, yeah, yeah that's it...
