I'm not sure I understand the point...other than it's shiny.
As a spool owner...spools seem mostly  pointless. If you're just going for speed and efficiency why not just run a stacked poppet? Recoil?
I can understand spools in terms of packaging where single tube is convenient, maybe ease of build on low end guns? Noise? but none of these seem to apply to tourney markers.
