Totally forgot about this topic I started. I'm currently using the yellow version on the crosses, and I love the control and pin point accuracy it adds to the stringjob( B5E on mains ).
Tested the graphite version and it's a tad softer IMO, and it lacked the control the yellow version gives me.
It's just my opinion, but I tested them side to side.
