Sounds like you doing the right things but if you are just starting out (and I don't know if you are), starting with soy wax can be frustrating at many levels. For me anyway, some of those FOs are a challenge even in a paraffin system but soy can be even more finicky. If there are some FOs that work for you, then you are on the right track, some will never work. Blending waxes can also be a challenge, sometimes you get the best qualities of both and sometimes you get the worst. In any case, you are starting over again test containers, wicks, and FOs. Some common blends are 50/50 or 70/30. That can be paraffin to soy or soy to paraffin, so there are 3 waxes to test right there. OR, buy a parasoy blend like 6006. I'm sure that there are others. Paraffin will help with the range of FOs that will work and help with issues like frosting but now it's not an "all soy" wax. All depends on what goals you have set for yourself.
