I have a WC Lathewerks stainless steel knob on mine and like it quite a bit. It weighs in at 440g. I wish I had seen this website you're looking at. I could have got the same design for even cheaper, and it weighs even more than the one I bought. My ST has kind of a notchy feel on the 2 to 3 and 4 to 5 up shifts even after the FSWerks aluminum bushing upgrade. I find the extra weight helps out a bit.
