Hmm.. if you mean by the SwM strategy that you would smoke a bit, wait 15 min or so, then smoke a full dose, SWIM doubts you would achieve as good/better results then starting with your primary dose, as DMT tends to have a steep tolerance spike, where smoked doses seem to have far less of an effect up to an hour or so after your last intake of spice.
The Key should not have any problems with reaching vaporization temperature (although the # of screens may need to be adjusted)
however, SWIM is also aware that changa seems (at least to SWIM) to be more effective then straight spice in prolonging a sub-breakthrough level by repeated smoking sessions
SWIM says once, he and several friends of his went out into the woods and smoked light doses of changa with a bubbler and maintained an enhanced visual/"godlike" state with minor time distortion/reverberations for well over an hour (got a bit too spooky for SWIM's friends when it got dark out!), but then again, it mightve solely been due to the fact that changa can be easier to smoke when out in the woods (SWIM hasnt really felt the urge to try to extend a normal pure spice trip.)
as for the taste of vaporized changa, it really depends on the herbs used personally, SWIM has only used electric sheep with lotus stamens, and its an acquired taste, like pure spice, but typically more enjoyable, especially when compared to smoking. Not quite sure SWIM would compare it to a hookah (water vaporizer might) because its been awhile since swim has used changa (uses it too quickly!) and SWIM personally can barely taste hookah vapor besides the nice moist-ness and fruitiness of the shisha used. (SWIM is sure essential oils or flavorings could be used to enhance changa flavor similar to Shisha! definitly something to look into, possibly add some glycerin to changa to improve moisture of the vapors/hide the plasticy taste.. or possibly a large communal dmt shisha to be used in an actual hookah for simultaneous space travel..)
May you find the Light... and bring some back.
