I've actually noticed the same thing. I must focus much more in shooting with low-kicks, but with mid-kicks I can just use pure strenght to get a some kind of shot off everytime. But in the other hand, just look how Patrik Laine shoots with his low-kick stick. Of course the technique is perfect, but there is A TON of torque behind that shot and I think the stick does exactly what Laine wants. I think he uses 87 flex and the stick is very long. Still he manages to shoot 100 mph slappers...But yeah, his technique is very unique.
