I also find, as per a previous poster's experience with breaking the ceramic wicks after they are installed, that because the wick hole acts a fulcrum on the wick it is best to be everso careful when attaching and tightening your positive and negative leads. i think, in this case, a little preparation can go along way. That's why I use only ribbon wire on my ceramics and I always pre-wrap then torch then pre-tighten before the coil even touches the ceramic. Also, with ribbon wire I will construct the prewrap with all the coils snugly touching so that if coil is a bit loose as it sits in place on the ceramic, and as long as I have enough vertical space left on my wick, I can gently tighten the coils by separating them at an angle to the RBA's deck. It's like stretching a spring, where as you stretch it, the inner diameter shrinks.
