So I have the vamo and protank setup. When I use it, it seems too airy. I also have a ego twist as well. When I use the supplies vanity ring on the twist the draw is not as airy and it doesn't seem to hurt my throat as it does when I take a draw with the vamo. The vamo draw is substantially lighter. Both are set to 4.8v and the vamo is in Rms mode. Any help would be greatly appreciated. Maybe there are vanity rings for the vamo? My vivi nova has zero issues with the vamo. Thanks
