Unfortunately colour can throw things out, I found that 16 strands of Red (very waxy) 8190 gave me the same nock fit as 20 strands of White (hardly any excess wax) 8190. Both were burnished to remove excess wax under 120kg of tension, and served using the same serving material.
"a thicker string should feel softer in the fingers where as a thinner string may feel like a wire cutting you "
I've heard this opinion from several sources and never understood it. Surely unless you are using a larger nock groove with a thicker string, the bit under your fingers is served to a diameter that fits the nocks, so however many strands in the string, the bit under your fingers will be the same diameter, so why would it feel different?
