I don't do patchouli, so I don't know about that one. I do have a harder time with pine type scents (bay rum, mistletoe), but was able to do Mulberry without a problem. I just don't offer those in this size. In fact, I don't routinely make this size in advance, and sell many more 4 oz and 8 oz candles. If someone orders one out of the scents I've tested in it, that's great. Otherwise I do a 20 oz tureen that I DO double wick (duh, they're huge lol). I know that I would NOT get as good a burn with c-3 or 415. They have higher MPs and this JUST works with 464. I fought with c-3 forever thinking I was a failure and then I switched to 464... whew... -Kristi
