Ahaha, I know what you mean by the game & where is the cop....
Blendmount is the way to go. Very solid and stable. I have a feeling the Countryjoy mount will cause the RD to bounce/vibrate on bumps/rough road as it has nothing push down on the RD. Not sure how the 8500 mounted using the suction cups, but for the 9500ix when I was using the suction cups I have to position the two little bumps on the top end of the RD against the windshield as support to prevent it from bouncing. I think that how it is suppose to be mounted in the instructions that it came with too. So after seeing the Countryjoy mount, I have fabricated something like the Countryjoy mount using a piece of 1/4" thick plexi glass and bolt the suction cup bracket (just the metal bracket without the suction cups) on and the RD bounces over bumps/rough road badly. On the 9500ix where the suction cup bracket (the metal) part slips onto the RD, there's wiggle room, it's not tight fit between the metal mount bracket and the RD. Since the Countryjoy mount reuse the metal bracket from the suction cup mount, the joint between the metal bracket and the RD is not any better, so I have a feeling that the RD will bounce/vibrate on the mount. Whereas, on the Blendmount, the spring/tension loaded bracket pushes down on the RD which creates a solid joint.
