Both effective fren! Need to work with the tools we have. I am more proficient in blasting really hard leg kicks, and liver punches. The physics of my shorter limbs works out for maximum torque, especially when I angle off. Mike Tysons side sweep liver punch....I practiced that so much and use it in sparring, its muscle memory to me at this point. Same for leg kick vs larger guys. I have short legs, but thick bones.....dense hard bones.
