the thermal mass of the Cloud is much bigger than that of the stems for the Solo. I think the important parts, namely the actual stem bowl, get up to temp in about 45-60 seconds? Don't try this, but I put a stem in once empty to let it get to temp while I prepped my goods. Went to remove the stem and being careless burned my finger on it. I don't know that I'd ever sacrifice a full session to heat soak a stem, and I too get to take my time more often than not. Sometimes I'll nurse the same stem load for a while, it's easier with the GonG since I can leave it attached, but I'll take a few hits at 7 and cool the stem down, then come back and do a few more an hour or so later, etc. This is with a power adapter as I don't want to be hard on the battery but I can definitely get good results without using a 12 minute heat soakJust speaking from my personal experience, plus I am never in much of a hurry anyway. Try it out for yourself if you get the chance.
Just throwing this out there but people pre heat their EVOs for 30 minutes.
Plus the Cloud uses the "stem" as the point where the air is heated, compared to the Solo's heatsink. The Cloud bamboo has the heating units around it and thermal mass takes longer to achieve.
Anyways, you're right about whitewalling. I was just doing that, ~.08 finely ground at 7. If heat soaking works for you, don't stop doing it. I don't really believe in "one size fits all" especially on something as subjective as vaporizing. I heat my stems with the flower already inside so I can get the hits quickly, though I guess I sacrifice taste hitting it over and over and cooling it at 6-7.
