Dynavaps give me the best flavor with my concentrates. In part, I think it has to do with vape technique.
With most other vapes, I draw vapor directly into my lungs. In contrast, I use the mouthpull method with my DV's and I think this allows the vapor to spend a little more time hitting the taste buds and nasal passage and giving me a lot of noticeable flavor. I can also notice the drop off of flavor after the second or third hit as the terps toast away, but that is expected.
I enjoy taking a small glob of resin and dropping it in a little jar of cbd isolate powder. The isolate dusts the dab like an old fashioned gumdrop. Wrap that in cotton and you have a balanced hit with the resin terps shining through. The first few hits taste like candy. I haven't vaped flower in quite a while now. Concentrates are a much cleaner experience IMHO. There is less mess, less odor, and less little bits of abv shit flying around. You don't have to blast your dabs all at once. Using a vapcap, you can sip vapor at your own speed. YMMV
