Hey muffin, the nv-g nautilus is an amazing real light fully sealed drag system. The hardy is a nice reel but the nautilus drag system is something of a trouts nightmare.
Down side to nv-g is price vs the dd, and nv-g is a little over kill for trout... If it were me I'd go with the nautilus fwx as the drag is just as good I have several fwx and and haven't had any issues.
