Okay. So why can make it easier? Isn't it the same when I use right hand?
Or the key is to 100% practice? Can you tell me algo you used for Z and H for OH?
Cheers
Try turning the RIGHT faces with your RIGHT hand, then try doing it with your LEFT hand. Unless you have some thumb on steroids, it's without a doubt that it's easier to manipulate the right face with the left hand. Face it, it's easier to use the pinky/ring finger than the thumb.
Search around for 2gen algos for Z and H.
