King Kong Kolas - Yes, I have used fresh frozen material before. In fact this is my preferred method of making hash. I have found that if you get it right, the bubble hash made with fresh frozen material tends to have a much better flavor and can be considerably more potent, at least in my opinion. Mine usually comes out very viscous and sticky and looks almost more like hash oil in appearance.
However I think that you do need to make a few adjustments to the process when using fresh frozen material to make it really shine. Also, the yield was always less than when using dried and cured material. However, I think this may be mostly due to the extra relative volume from the water that is still contained in the undried plant material, so it just looks like you are using more shake when in fact you are not.
Of course what is the "best" hash is subjective, but I far prefer good fresh frozen bubble hash to the dried bubble hash most of the time.
