Got the bumper from Rover's North - Proline RNA2106. I went with this as it had the holes for the headlight washers, and it doesn't stick out as far as the ARB bumpers. I did not relocate the windshield washer reservoir - I left the driver side wheel-well cover and used some of the passenger wheel-well cover (that was going to be discarded with the bumper change), use a heat gun to bend the wheel-well plastic to cover the reservoir and attached it to the bottom of the new bumper (drilled holes/bolts-nuts). Winch: VR EVO 12-S little bit of an overkill... Did have to modify (cut) the grill to fit around the winch but otherwise, no modifications and fits well.
I wanted a close fit, again not sticking out so much. Rovers North did have a close fit bumper that would accompany a winch, but I believe you have to remove some OEM brackets and maybe even cut some metal below the radiator to accompany a winch of this size.
Pictures attached.
