Had my 17 z500 apart last week to reclock to b2, which I am very pleased with, I did take the primary apart to clean it and I weighed the sliders, mine are 14g and grabs at a pretty low rpm compared to what my new c600, that only came with 10g, so I left the z alone, I did get a set of 14’s from the can-am guy and the 600 is so much better now. It’s all owner preference, if you change it and don’t like it, you can always go back, good luck
