If you have 6 micron DLF, I have that too. I decided to add 3 micron DLF, then 5 and 3.5 micron leather strops. I am happy, but honestly considering kangaroo leather as further strop refinement at a lower micron level than 3.5 (maybe 1 and 0.5 micron) but time will tell.
Honestly, learning more about sharpening was the biggest help to me over microns, stones and stropping. Getting an apex and managing the burr is more critical than any micron will ever get you.
