I used BC scents as well when I first started with soy and I couldn't get them to throw either. I use GB 444 wax. I didn't spend any more money or time. I changed to Justscent and Alabaster and now my hot and cold throw are awesome, if it doesn't work for you move on. It might be your wax it might be your scent, it might be your pour temp, it might be the alignment of the planets, with soy you just never know.
