Anyway, looks like the issue was the B-tension, I reversed it and now all seems nice and Quiet on the stand
I will get a longer screw and try to thread it from the top (Probably M4 x20 or 25 mm)
The max cog and max capacity are separate specifications. Just because you are within one does not mean you can ignore the other. 28T cog is the specified limit, you may or may not have success going bigger.
