I got a Nimbus today, mine has two holes opposite each other. The guy at the vapor store drilled them out for me on the spot using a 5/64 bit. This thing is very airy to me. After adjusting to the air flow I'm getting the plumes and flavor I was looking for. I'm finding that If I setup the air holes so that they line up with the coils I dont get as strong of a throat hit. BTW I'm using 6mg and 100% vg. I'm also using a nice thick layer of cotton on the bottom with nothing going through the coils. The guy at the vapor store was blowing plumes and I told him to set me up with that. It seems strange to me to not have a "wick" but I gotta say this Nimbus is rocking.
