Once again, I'm toying with the idea of going back to an 8500 x50.
Currently running a V1 @ 3.826.
Any reason to go with the RX65? I'm rather partial to the 8500 for one reason or another, though I wish the windshield mount were more like the V1. Steep windshields, like on C5 Corvettes, don't play nice with that flimsy thing.
