Ok long here so get ready, I have been testing the 4 oz tins from peaks, ecosoya 135 and lx wicks. I've settled on the 16 or 18 depending on fo. I get great pours and cold throw, but no hot throw. I thought this was because my testing room (12 x 16) was too large for the little tin. Well I got a candle warmer on sale to try out, never used one before, set my tester candle of peaks cucumber cantaloupe on it and wow, the entire upstairs is smelling good. So a scientific question would be why is there such a difference between wick burning and warming when it comes to hot throw? More practical question for me is what wick comes close to the lx16 and lx18 for me to try? Sami
