In need a new "N" axle for OTK, USE OEM OTK axle or Swift?

need a New “N” axle 50 MM for OTK, USE OEM OTK axle or Swift?
Price difference does not matter to me,
Does the Swift axle work the same as original OTK axle?

Thanks Jim

Performance Kart Technologies straightens axles for $55 + there and back shipping. As it happens, I currently have both axles you speak of on their way back to me from PKT and I personally couldn’t tell the difference between the two on the kart.
