I, too, re wicked the heads I have. 32 gauge kanthal with a five over four wrap. 2.6 ohms resistance. I used worsted cotton yarn for the wick. Right now it's doubled over and pulled through the coil. No additional wick needed. This setup has stopped the " end of tank" flood. I've not had a dry hit. I do have good clouds of vapor that are consistent from tank start to finish.
My vamo at 3 watts/3.0 volts burned almost every stock wick. At first I thought it might be my DIY juice. Nope. Same juice in new setup is fabulous. I might be nuts, but I swear my juice tastes better.
I had a really easy time with the worsted cotton yarn. It seems to be perfect. Obviously, the yarn is no dye. I didn't boil it before using it. My wife provided it so it probably came from Walmart.
Questions? I'll help if I can.
