Calling Oval a knockoff is selling John Cobb a little short. John Cobb originally designed these bars while working with Hed and Lance then decided to go on his own business adventure. I've not ridden either but I wouldn't be afraid to take a good hard look at Oval. john Cobb has done great work as far as aerodynamics go (ie the oval fork). If ou wanted you could cut the oval extensions down I'm sure.
