Waxy DMT should be fine.. acuminata extract is always a pretty smooth smoke in the GVG.

+1 on xylene. But I'd personally just pull with xylene to begin with and then clean it up with naptha afterwards if neccesary. Shellite/naptha requires heat and also you need to have it saturated enough to precipitate all of your DMT out.. If you pull with xylene first then you have all of your DMT in the one place and you can then dissolve in the minimum amount of shellite needed. Or you can salt your alkaloids directly out of your xylene with dilute acid and then re-extract via the addition of NaOH and fresh solvent.

Since shellite in Australia is such bad quality it always adds doubt in my mind with the initial pulls. It just doesn't seem very efficient. Xylene, toluene or DCM are much more trustworthy IMO.
