Use the Mk25 chutes along with the radial chutes. The regular chutes have a nasty habit of ripping spacecraft apart when they deploy at high speeds, and they deploy too late on Duna to do anything good.
I think the 48-7S needs a slight nerf, but the 24-77 or whatever (the radial one) REALLY needs to have a higher specific impulse instead. Why are drogue chutes so big anyways?
