considering the full time job, side hustle, and young family, I think my answer to that question is "sleep".
But I shimmed two of the six splines. It's an okay balance between performance and noise.
I'm considering ordering a full spindle pack (that's the spindle, quill, bearings, and spacers) from LMS and rebuilding to factory specs. I have another thread regarding Grizzlys version of my spindle not matching their drawing...and maybe that's been the issue the whole time. The $300 is far less than the amount of time I've put into getting this "perfect"... then again the new parts may exhibit the same issue.
