I think the HTP's curl to much. Have you all had a problem with them, or is it just me...I am looking more for a wick that burns straight. That is why I like the RRD's and Cotton core (from peaks.) So far I have tried the LX, CD, Hemp, Performa, HTP, RRD, Cotton Core, hmmmm I am sure there are more but am not thinking of any... Geez the darn wicks hehehhe. I am using the Ez Soy.
