I recently picked up a new/used 810e with the latest (Andy's) bracing. When compared to my 2011 916ce with Adi CV bracing, I find the older pattern is a bit brighter but also some stronger midrange overtones. The 810 seems more balanced with stronger fundamental presence and more controlled overtones. I've described its voice as more "sophisticated" -- I like it. As for forward shifted/relief rout, my main gigging guitar, 2014 416ce, has that pattern. A bit brighter than the 916ce, it has more zing in the upper register and definitely more "bark" to the voice. It seems the loudest of the three to my ear.
All three patterns are definitely recognizably different from each other, but they also each have qualities that sound very good to my ear. Variety is the spice of life!!!
