Replacement drive train time

[z1ppy]

Anyone want to confirm I need a 53mm chainline SM-CRE80 front sprocket, as the Vitus is a boost frameset? I'm pretty sure this is correct, but would like it confirmed. I like the idea of 11-46T cassette but considering my current cassette is looking pretty ****ed up, with teeth missing from the outer cassette sprocket, and it's not like I run out of gears that often, I think this might be just silly?
Anyone changed their gears yet and gone a different way?

I have changed my cassette twice, but stuck with the same spec, as cant see need for a change. I do want to upgrade the shifter at some stage to an XTR, but haven't got round to it
