I like it. I noticed the whip stuff with knockdown assault the other day when I was thinking of making an indiana jones-ish character. I ended up going in a different direction, because I like the idea of an angry half-orc whipping baddies to the ground and then punching them with a spiky metal fist.

The spiked gauntlet is the other weapon mostly for flavor, as I just can't get behind the idea of double whips as a scary arsenal.
