I think that marathon has a brand new sterling, these come with very light hammer and valve springs. It is a completely different animal than a proline sterling, with adjustable velocity and all. for consistency arrow recommends 600-650 psi hpa
If he goes and drops a cut spider spring in it, it will do nothing positive for his marker or his pumpstroke.
