So, I'm not here to dis the bubble stone, and I'm definitely going to try the fc-2000 when its not a horse race to get some. I want to summarize, quickly, my fishstix experience, as bits and pieces of information are disjointedly floating around. I had no break-in time, my coils were full contact. I started at 1.4 and 1.7Ω and found it to be a good vape. But as I built lower res., I found that the wicking properties of the air stone couldn't keep up. I have visually compared wicking properties of air stone and 500 ss; 500 is faster. I built a 9/64 fish stone wick with an SLR coil (.7 i think) and hit a point where the wicking abilities were sufficiently unsatisfying that I decided this wasn't the material for me. All this time, over three/four days, I became aware of the presence of a flavor (call it artificial stone-like) which I found unpleasant. It was very subtle; but given the wicking issue, the flavor didn't help. Also, yes, my SUBJECTIVE experience was that the gray stone (TopFin sku #3725702195) began to look more blue. It could be lots of factors (wetness, camera, yellow juice); but my experience was that the stone looked more blue-gray than when it was out of the package. It doesn't much matter. I had already dismissed the material for MY PERSONAL choice based on the previous factors. Here's some picks, the wicks in the tray (in middle pic.) are as follows; central ones are all used, one on far left unused, two fat pieces on right unused. The coil in the AGA wasn't a keeper (not perfectly tight). The coils in the tray (middle picture specifically) are the low res. tight contact, which I found wouldn't keep up.
