Bill - Since you already have a batwing CVO, I'd be inclined to go the Road Glide route. The fixed fairing really is that good. If you plan on keeping the bike for a substantial time, the 10 RX will allow you to build it your way and have a truly one-of-a-kind ride. I'd would personally opt for a Black Denim RX, Night Train-like black-out treatment, tasteful custom paint enhancements, and a 107" build. Gonna end up costing close to the same as a CVO by the time your finished, but you will have enjoyed the pleasure of building it yourself and never worry about confusing which bike is yours in the parking lot.
It took me almost $5k to get my SERG mechanicals where I believe they should have been from the MoCo. Could have built a nice 107" for similar money. Don't really want to paint a CVO so it continues to look like most other SERGs, which are beautiful, just not sufficiently unique. However, they do maintain better value than a custom build.
Good luck with your decision, you really can't go wrong with any of the options that you are considering.
