I've been making my tarts with KY pillar/votive and my containers with KY125 (adding 3-4% BW). In my humble opinion, I think the overall appearance of the tarts are much better with the pillar/votive wax. They just look more professional to me. A friend suggested that I should mix the pillar/votive with the KY125 for tarts, I haven't tried that yet. I just figure that for now, I'll stick to the pillar/votive, I'm happy with it. You know the old saying . . . if it's not broken, don't fix it.
