I've arrived at at the KJH after a long search for a blade. I grew up with playing 5 ply all-wood blades but have changed to composite blades in recent years to find a larger sweet spot and also some extra speed for the bigger 40mm balls, especially now plastic.
The KJH plays extremely nice. It has a heft (mine is 91g) and a solidity to it that is hard to describe. The blade is very linear so you don't get surprises when you hit a soft or a hard shot. The blade behaves very much the same.
I would put the KJH at the very upper end of OFF- or at the lower end of OFF (probably the latter) in terms of speed, but because of the above, you never have the feeling that you can't control the blade.
