Hopefully it will come today.
One thing I didn't mention which is significant is that I'm using my vape for a variety of herbal blends I make and tobacco in addition to marijuana. Most of you seem to be using exclusively marijuana. One difference this makes is that packing material in the elbow is not always feasible as many of the herbs tend to fall out due to their different consistencies and shapes. So I really need some kind of set-up with a sizable bowl and screens on both sides of the material. Can anyone comment on the size differences between the ELB bowls and the DDave adapter combined with the elbow screen but not using elbow pack?
As for flavor, it is the tubing which has a terrible taste. hitting the elbow directly tastes fine. I've now attached a couple of the EQ mouthpieces straight onto the elbow using just the short (half an inch long or so) pieces of tubing that came with the vape. The mouthpieces and the elbow all touch each other. The tubing is just used to connect them together. This set-up is not bad, and it's an all glass vapor path right out of the box. I'm wondering how much different the taste will be with the silicone tubing that has been recommended here several times (from amazon) compared to an all glass set-up. Maybe I'll just have to try it out, but any opinions are appreciated.
