I used a RAM Mounts X-Grip with Small Rail Base to mount it to the window support bracket in my 23 LSV. I also installed a USB charging port in the walkway storage area. That way I could charge the phone when it was in the holder. https://www.rammount.com/part/RAM-B-408-37-62-A-UN7U

Ca anyone explain the difference between Black Metallic and Silver Black Metallic? Which one is a deeper black and which one has the most sparkle?

I second the Phase 5 Model X. It's a great board that will really improve your surfing skills.

I'd say go with what Jim is telling you. I talked to him a season or so ago and followed his recommendation. It made a big difference for my boat and set up. Jim knows his stuff!
