I got the King in today, and boy does it hit hard! It does live up to the general consensus about it hitting like a truck. Very solid. The threading is similar to chi, but i like the chi's a little more, just 10% more. Contacts are great, nice and wide. I dont like the air control as much as the chis though. Its a little hard to use. I have to hold the top end to move it, unlike the chi. It weights about the same. The king is able to stand on the button without being fired. Even with the kayfun on top. Im waiting for my voltage meter to come in and to test voltage drops between the two and my other mods. I'll be updating this soon Thanks for waiting
