Well now, size, that's easy enough. My Nextel xc-1/32 is 1.5mm. The 2mm ekowool is . . . . . . . . . 2mm. (analog calipers, here, nothin' fancy). The ekowool, depending on how I squeeze and rotate it, can measure 2.1, 2, 1.9. So . . . . .2.
This, of course makes side by side testing (like IcyX up there wants to see) not so much happening. Tonight, I'm just doing general impressions on a low-to-medium demanding build. Here's my initial thang.
Remember, I am a Nextel devotee.
I set up the IGO-L with a drill bit wound 5/64" coil. The moistened ekowool slid/corkscrewed right in there. So, @ 2mm it sneaks (head first) into a 1.98mm hole. This is same as when my 1.5mm Nextel snakes its way into a slightly smaller than 1/16" hole. (I think I managed a fat 3/64" hole once).
We are at 1.8Ω. I put a few drops on the tail of the wick and watched it suck the juice up. It wicked surprisingly well. Here's where I get REALLY scientific, Kids. The Nextel wicks better than the Ekowool. How much? Not enough to care in a dripper scenario. Lets just say, "a little better"
This relates to the next observation. The ekowool is swelling a little bit. How much? Not too much. The Nextel almost doesn't swell. I would venture to say that the Nextel wicks better by the same margin that it swells less. (makes sense, right?)
The first vape: This ekowool is GREAT in a dripper. Basically flavorless, nice, "invisible". I wouldn't be able to differentiate these two wicking materials in a blind-dripper testing.
Ok that's all for now.
Maybe Commie will come through on the pictures, science, yada.
