My real issue is not with an opponent who anticipates it, but an opponent who has any clue about what you're doing. Anyone with a 5th kyu in Aikido can tell you what the technique is and anyone with a basic knowledge of ukemi can escape it.
As John Matua (a mediocre, at best, MMA fighter) once said, "a big only has so many moves he can use on a little guy." Matua definitely knew a thing about being a big guy, he was +400 lbs. It's about exploiting your size.
