OK, how about some wicking tests? Thanks to @B2L for the cotton samples.
For the moment I am just going to number the samples, with #1 being on the left, and so on.
This is the separation rig which was placed over a glass jar:
- All samples were exactly 0.11g of fiber, except sample #5 which was so dense it wouldnt have been long enough.
- All samples were properly fluffed according to their type.
- All samples were placed in a 3mmID spring, akin to one of our coils.
- All samples were placed in a rig that kept them separated and also not touching the walls or anything else
- Jar was filled with a 50/50 mix of PG/VG with some pro grade food coloring

And the race is on.....
Im calling #3 the winner, and #5 the 2nd place contender just because of how much juice was trapped in the fiber.

1-Koh Gen Do
2-VCC Vapers Choice (was probably the easiest to work with)
3-Rayon, big box from Sally's
4-Hemp
5-3mm braided Ekowool, considered the most premium silica
6- Native Wicks Platinum Blend
Now keep in mind that this is only HALF the story. With wicks we care about 2 things, capillary action, and flow. This only demonstrated capillary action. I am still pondering a good protocol to test flow.
Really though, from what I saw, anything but #4 and #5 would work just fine.
As promised, a follow up to the wick test. The first test was mainly to show how poor silica is compared to modern materials. The context being that poor silica performance might have significantly contributed to why Dr Kurt's Gen 2 results were so bad.
On this test I took the 4 best from the first round and matched them head to head.
Test Conditions:
- 50/50 PG/VG mix
- each wick trimmed to about 1.5 inches
- 0.11g of fiber each
- Coil (spring) was 3mm ID
- All set in a rig that kept them suspended without touching the walls.
- VCC Vapers Choice
- Rayon
- Native Wicks Platinum Blend
- Koh Gen Do organic cotton pads (outer skins removed)
Results:
- Initial Capillary
- Rayon
- Koh Gen Do
- Native Wicks (actually a very close 2nd IMHO)
- VCC Vapers Choice
- Capacity: (defined as g of fluid held in the wick after 1 hour))
- KGD - 3.22g
- Native Wicks - 2.69g
- VCC Vapers Choice - 2.13g
- Rayon - 1.72g
I am sticking with my rayon. Other factors like flavor, longevity, and scorch temp still make this my fave.
