I expect to see slow practice when you learn new techniques. But when you practice lets say 2 years, I'd rather see you practice full speed all basic techniques. Unfortunately, due to lack of competition, one can see very often, ppl in peak age with 10, 15 or 20 years of experience still practice slowly all techniques as if they are 95 years old.It is valid to both roles: nage and uke. Seems like everyone wants to become O sensei without too much physical commitment.
Such situation helps a lot to build many ilusions as we have proof oth that on Aikiweb forums..
