I got my kayfun Lite a couple days ago. I'm a huge kayfun fan love my 3.1s but man this lite is the bomb. The draw imo is perfect. Much like aj said, not too loose, not too tight. I feared that the draw would be super airy which would be a deal breaker for me, but no not at all. It's just about perfect. Feels like 1.3mm to me if it were a genesis. No leaking and I really like the shorter design and the fill screw vs. valve makes me happy. The valve is a point of failure, as much as I like it, and love my 3.1s it's the truth. The lite eliminates the worry. Time will tell I guess, but I'm calling this one a winner
