I actually like the af in the Zeus. It's just so smooth with no turbulence. I find the Crius a bit restricted due to the amount of wick in the channels. Have a cold and not wanting to mess with my wicks too much. Much better tonight so I'll wash all of them tomorrow just in case. Going to play with wicking in Crius. Looking forward to trying out my new coils from AVS. The subjective nature of vaping never ceases to amaze me. As complex as people's taste in food and literature.I am using my Zeus this week as I am determined to get acquainted with that tank. My first outings with it were not successful but I think I finally have a build in it that works well and have it wicked just right. I am enjoying it. It is not as airy as the Crius II but I got used to that in a day. We shall see how it goes. For me, Ni80 wire works better than SS - it is less springy so easier to position the coil in the Zeus.
