I choose a wax that I could get locally to save on freight. As far as scent throw goes, if a scent does not throw for me, I will try the same scent from another vendor or two to see if the scent will work in soy for me. If all of my scents fail from all 3 sources I do not carry that scent for soy. I used to color my soy but after battling with frost issues I made the decision not to color on my standard product line. I will do custom color jobs if requested.
