I used to be a fan of the 1343 but realized that it holds very little FO, thus the intense sweating with mottles...or when burning any type of candle I made with this wax. In addition, I never got a very good hot throw with it. I switched over to 4045 and found that I could add much more FO...1-1.5 oz. per lb...and not have it sweat it's brains out. You can make all of the same types of candles that you do with the 1343...but...without all of it's drawbacks. I'm not putting 1343 down completely...I'm just telling you my experiences with it. Other's have been very happy with this wax, but I bet if they compared the two...they just might consider switching.
