The results are finally in! A big thanks to all of you who helped make this possible. Particularly to Olaf in Germany for doing the actual testing. He goes by Cuetips1000 on youtube and was kind enough to not only do the actual testing, but to also do a video. He did multiple tests on each material but informed me that he edited out the duplicates as the results were all consistent. Some very interesting results! Perhaps they jive with what you all have experienced...
