I hated the GPR. I would go with the Ohilns. There is no need for a steering damper! 140+ mph over a hill wheelie, almost highsided on a track without damper no issue coming out of the big moment, went off the track at 70+ mph dirt and all with no wobble/wreck. Just saying! I did get a small wobble once comming of a 100mph wheelie, but the bike wasn't set up and tire pressures were off a bit. Adjusted suspension, all has been good..knock on wood!
I know what it's like to ride with that peace at mind. Go with the Ohilns!
