I knew about the Reo. Sounds like the story line for a 70s movie. Didn't want to say what type. People are sensitive here sometimes. I'm going to take a look at that mvp..
You should be fine with the stock heads at 60/40, Eric. The only juice I've had to remove wicks for was Boba's and a 20pg/80vg I use. The nice thing about the Kangers is the multitude of options available to suit every user. The heads are cheaply replaced and/or with a bit of time and patience, easily rebuilt. Obviously you're almost always going to get better performance from these little guys with a self-made wick and coil. I use 32g kanthal and Aunt Lydia's. Most recently I've been experimenting with using ss mesh in the protank. Very happy with the results so far, nice clean flavor from the ss, and I just use several strands of bamboo in place of the flavor wicks that sit on top of the coil to prevent flooding issues. It doesn't gurgle, it doesn't dry hit. I've TRIED to make it foul up, and I can't!
Check out Todd's review and rebuild of the eVod head... It's the exact same process with the protank since the heads are practically the same, so you can get a good idea of what's in store if you decide to rebuild your own!
Also, with the protank, if you restrict too much airflow at the 510 stem, you're probably going to gurgle at some point. Think if you tried to drink a milkshake through a straw with a hole in it. The larger the hole, the less of a chance you're going to get any milkshake. Plug that hole up or make it too small, though, and you're gonna end up with a mouth full of milkshake. The gurgling is a result of excess juice buildup in the center pin of the head due to either not enough wick to soak it up when it drips back down, too little airflow, or a combination of the two.
I'm not up on thread sizing it's pretty confusing.. I'd love to hear your method for rebuilding the heads. Do you coil first and then slide the bamboo or do you coil around it? The size 10 sounds like it's between 1 and 1.5 mm since I saw the a 1.5mm needle is recommended does that sounds right? How many strands do you use in the coil?
Also do you have any issues with the flavor? I have some 2mm braided bamboo that wicks really well (awesomely actually) in my evod heads but it takes forever to get rid of the earthy taste. I've boiled it countless times with the same results...
Thanks!
