i don't see why combining the two solvents for salting would cause any issues...though if anyone has evidence of the contrary please correct me  - i've heard its not good to combine solvents to pull alkaloids and can cause weird reactions - but i'd presume salting would act differently as the alkaloids would already be in each solvent and its unlikely that the two solvents mixing together would suddenly alter/degrade them (though with time maybe?)

although i don't use it often anymore, i've found with shellite that it pulls alkaloids more effectively when the alkaloids have been salted out and rebased in a new solution. for crystalisation salting and rebasing simplifies the solution that the solvent comes into contact with, and reduces it to basically water, acid and alkaloids ..

people should consider whats more worth it though - a nice looking product that lacks in other desirable alkaloids or a full spectrum product which doesn't look as nice physically, but (subjectively) is deeper in terms of the experience on offer.

at the end of the day dmt and friends are better for vaping than staring at in a vial.. after a deep experience I bet you'll hold your extract in the highest regards no matter how it looks.. though it is nice to have some pretty crystals sometimes. i'd at least advise pulling with a less selective like toluene or xylene and then re-acid/basing/pulling with shellite if you really need crystals. then you can pull whatever is left in the solution with the other solvent afterwards to experiment with and figure out whether you want it in the extract as a whole
