Yeah, Obi-Wan takes it, even as a Padawan he's gotten the best of lightwhip users before - albeit Ona Nobis isn't as skilled as Lumiya, but still. Kenobi's familiarity with the light whip and skill gives him an edge. at least IMO.

I'd think Soresu would also be a pretty viable counter to the lightwhip.
