I am convinced at this point that this Sunrace cassette is an example of you get what you pay for. The cogs and built in spacers are not manufactured precisely enough to get accurate shifting.
So now I'm going to settle in and live with it for at least a year before I 'earn' the right to spend more money on a higher quality Shimano or Sram cassette.
The Sunrace cassettes are fine.
Did you check your hanger alignment with the Goatlink hanger extender? It is likely not straight which will affect your index spacing.
And even if it is, you took a derailleur designed to keep the upper pulley close to the cogs and moved it down an inch to where it is only close to the 42t. Of course it isn't going to shift as well as designed.
What spacer are you sanding down, and why?
Generally, any project undertaken by a man with a mallet is unlikely to succeed. Do you know how to check the hanger alignment?
