I'm looking to put a 898 at my console of my Stratos 294xl. Can someone give me suggestions on which Ram Mount to use?? I see there are different size balls and materials. I went to the site and they suggested Ram-D-111U-C 3x11 base with a 2 1/4 ball and a 3.68 round base. Looks like a metal material. Looking for input and possible pictures of your mount. Thanks in advance for your help, Jeff
