I ran the 0.7Ω coil that came pre-installed in the nautilus 2 (13 watts with my DIY vanilla ADV) for about an hour before I tossed it in the garbage. I found the flavor to be muted, much like the clapton BVCs. Those who enjoy the clapton BVC coils may like the 0.7Ω coils, but they're just not for me.
