I think I may use both when I make mine. I am going to let it cool down after it is done to test how thick it gets. I have noticed that I like my finished product to move a little in the cartridge as I do not get any clogs at all when it is like this.I do not winterize rosin. That completely defeats the purpose of making rosin. A solvent-less extraction.
I made a gram of rosin/SerVm oil following the instructions to the letter. It is too thick and stopped vaping. I have enough of the sample to make another but I think I will use an equal amount of Liquefy this next run. That will still be a low ratio of thinner to rosin. 1 gram rosin .2 gram thinner.
I am well pleased with Liquefy at about 1 gram rosin to 0.75 gram (or less) of Liquefy. I just depends on the rosin. I start with .5 gram and bump it up to honey consistency.
