I know what you're saying too, and it makes for good technique. But I remain a realist and for me, that good technique offers a faster route to pain, should you chose to take it. The more choices you have the better.
folks have different ideas on what is good techniques. you have
good = lots of pain on uke but might or might not affect uke's structure/center/ability to counter
good = little to no pain on uke but affected uke's structure/center/ability to counter
lots of space in between. personally, i work toward the little to no pain approach. doesn't mean that i cannot cause pain; however, the pain that i can cause won't be localized to the wrist. it will be multiple places on uke body at the same time. sort of pain on sale, buy one gets two or three for free.
