Thanks. Silica is much cheaper by the foot, that's why I was wondering if Ekowool was worth the price difference.
For this particular application, no I dont think it is worth it. Because trying to thread Ekowool through an exsisting Triton Coil is going to be a serious Pain in the ..... It has some slightly different size shape thing going to it, than regular silica. For a RBA/RDB then yeah maybe it is worth it to you. While I havent done any testing myself to prove this, I understand the capillary action principles and the difference in design between regular silica and ekowool, so knowing these things, Ekowool will have a greater capillary draw (wicking), so it will pull juice faster and in larger quantities than regular silica. Then you factor in the fact it last longer than regular silica and cotton. Really it all comes down to application and to taste.
Although, I do wonder if Halo's wicks are of higher quality as they come ready to go in the coils, and the replacements require a torch-burn for better flavor according to the reviews I've been reading.
Well their stuff i would say is of average quality. You can do a bit better if you get what is known as double twist silica (AKA German Silica).
Basically with silica, be it "regular" or Ekowool, this is the rule of thumb... the more complex the joining of individual strands the better, because this gives it better resiliance it also increases it potential wicking factor. So... the more twisted it is the better, and woven/braided (aka Ekowool) even better longevity and wicking properties.

Now just to confuse the issue... with what i know so far, and what i have learned through trial and error. If i was inclined to rebuild a triton coil head totally. I would use 1.5mm hollow core ekowool as the coil wick, and 2mm cotton core ekowool as the feeder wick.
