Another vote for ECBlend RY4.
I bought a 4oz bottle of XF (extra flavor).
I am using it to get rid of liquids I don't like.
50% RY4 then 40% (currently Dekang USA red) and doctor it with more RY4 caramel or vanilla.
Of the 7 RY4's I've tried I also am kind of partial to the Mom and Pops version as well.
