I'd simply take inhuman strength with it, which would result in a similar cost.
Strength isn't worth much, if you don't have the leverage to employ it. You might be able to grab someone by the wrist and throw him, but if your opponent is quick enough, he can simply lift you off the ground and you can't do a thing about it. Of course you can then simply squish his wrist until he lets you down again, but that is another story.
