Hi kandlekrazy, I love C3 but yes I require a firmer product and do not want to change wax as I love the C3. I am in Australia where it's very warm and humidity is very high and also I can only seem to find the suppliers stocking UA however after reading many posts on here it's apparent I would require USA if I wanted to use a hardener. Also I'm hoping it will help with wicking - or at least make it alittle easier. I do find c3 harder to wick. I have made a blend of 90% c3 10% pb yesterday. I'm letting it cure. The tops are perfect and CT amazing - let's hope for a great burn with great HT.
