I started to feel much more comfortable in OW climbing after visiting plastic surgeon. They do now so call asymmetric limbs surgery . I did enlargement of my left fist , enlargement of right knee and liposuction/[decrease size]of my right fist and left knee. Having left fist size of #5 camelot and right knee size of #3 camelot [ the call it Donini knee] make a possible for me to climb any OW as a fist/hand crack with secure knee stack . Asymmetry is especially helpful for overhanging OW. It make hand stacking and inversion redundant. I also improved my butt/foot size ratio increasing my foot size to 12 and liposuction of butt to size 28. With this size Hartouni rating of Ivory center as 5.7 is correct. Plastic surgery make climbing more enjoyable for hard finger size also. Having asymmetric hands and fingers eliminate rattly fingers problems and make any thin crack pleasant lockers all the way . So now "size matter" is not applicable for me.
