I use POB for my melts and rarely have a FO that doesn't throw with it. I use oils from NG, CS, FC and RE. I heat to 190-195, add FO at 180, stir for 2 mins, and give it another quick stir when it reaches the 155 mark and then pour. I use between 6-8% fragrance load depending on the FO and it's awesome every time.
