My Xeta setup is widest air/no chimney reducer with a 0.5 Ohm fused clapton 2.5 mm ID. It's by far my driest ever BB setup. I can go a week without removing the Boro and even then it's only a few tiny drops of condensation. I've got most widely available BB RBAs and the Xeta beats them all by a fair way for my style of restricted DL vape. Great flavour
My sxk haku zeta flooding issue was my fault. I wicked it like the insider for some reason. Rebuilt it with the cotton coming out the wick slots and trimmed it close, then fluffed. Now that issue fixed. Clear boro black gasket issue is better with 2nd black gasket but not 100% gone. I tried the haku with no chimney insert and got hot splatter on my tongue.
