Jonah300, I was wondering the same thing myself, I have the Frankie May for heavy oil and it definatley works, I find also it will work well on medium oil as well, can play it tight or swing it out a bit. Problem is I don't find heavy oil too often. So I was wondering If I shined it up if it would react like the G-3 or should I just add the G-3 to my arsenal?
