Yes, this is something the GrassHopper folks should be mindful of. If it relies on any amount of conduction, not only is flavor going to be an issue when using a full load, but there will also be those who will be disappointed with vapor production when using small loads — see: the Ascent thread. And, I imagine it would not be as easy to Jerry-rig together as effective a spacer as the glass flowers were over there, given the shape of the bowl here.
I particularly wanted to quote your post and chime in because I saw @
Zenpen didn't 'like' your post and then 'liked' Fenton's post questioning you about it... It really all comes down to the most hard to believe claim: that it is truly a pure convection vaporizer, having such a small size.
And, just for the record, .5 grams sounds like
a lot to me. My usual loads are between .07 and .2 grams. My video in my sig is one example of how far a small load can take you when using pure convection. (
