The Chronarch spool can go a bit lighter lure-wise and seems to start up fast and stay fast. It's an excellent caster for distance. Plus it has some knob bearings and some bling that the Curado I lacks. The Chronarch palms nicer to me, I think because the Curado has a larger or lower gearbox or something. I also really like the Chronarch's knobs, though I think they may be on the Curado 70 as well now.
