I heard some rumblings of Unknown putting out a proprietary 6.5UM cartridge with a 40 degree shoulder. I was under the impression that their 6UM was their baby and they figured that was the best of the best? I had also assumed they had probably went through the paces and had tried the 6.5 before stepping down to the 6. Am I late to the party or missed it in a different thread? Or is this completely a lie and there is no such thing?
