Hey all! I'm a karate instructor in Hayashi Ha Shito Ryu and have been studying this particular style since 2000. One fairly unique aspect of Hayashi Ha Shito Ryu is the manner in which we perform the jodan uke, otherwise known as age uke (upper block). In Hayashi Ha Shito Ryu, the "blocking" arm is chambered and delivered from the inside of the opposite bent-arm (bottom of fist against biceps), as oppose to many karate styles, which chamber/deliver the arm from the outside of the bent-arm.
Any thoughts on the advantages/disadvantages of this from a practical application perspective? I've tried to mess around with the applications from the latter method (not used in my style), but obviously, given my habitual training, it feels so unnatural.
