There is an issue with runway crowning and landing a long jet here. There's a 2 degree crown from the centerline to wick water off the runway, so if there's any drift off of centerline (or the nose is lined up with centerline and the CG is not, in the case of crosswinds in a long jet and not consciously compensating for this) you're running the risk of scraping the upwind pods as you flare for the relatively lower downwind side of the runway and subconsciously put a degree in to stop the drift and get back to center. Be careful out there :-)
