Wohooo this is the stuff me and Stella have been discussing for weeks. For me 45 ply works also, but I too think LX and CD is the way to go. I never tried eco but the jumps in eco do suck. Stella knows her stuff! I too will go to CD wicks. But I may do LX. I will see. Sometimes I make the candles in such a ay that no shell is left, its bright and the candle looks ugly when burned.
