With the drops pointed down on the V20, I find I have to work at gripping the bars to keep from sliding off. I have a bar end mirror on the left and the post gives me a place to rest my hand.
That was part of my motivation for the flipped then rotated Gary bar configuration: I also felt like my hands could slide off the bars if I relaxed my grip a little, and especially if I hit a rough patch of road. I had them positioned like yours, with the grips pointed almost straight down since that provided the most natural wrist position, ie, straight as opposed to adducted which is what occurs with the grips in a more horizontal orientation. With the bars flipped and rotated approx 90degrees, the grip area is still straight up and down, wrist is straight (or 'neutral') and there is no feeling of possibly slipping off the end of the bar. Much more relaxing, even when taking into consideration the disappearance of the 'death grip' which comes with getting used to the fwd/mbb. Maybe that feeling of possibly slipping off the bars is an irrational fear but I had the same feeling with the Bacchetta tweener bars; i put stubby MTB bar ends on those to provide hand rests and put my squirrely mind at ease

Having the Gary bar end grip areas vertical seems to me to give the best ergonomic position for pushing or pulling on the bars. A Gary 2 or maybe a Gary Sweep is better than a standard road drop bar for reasons shown elsewhere and better than a Soma Junebug or Midge On One bar due to the more pronounced outward flare of their grip areas.
So, the flipped Gary 2 solved several problems for me. When I sold the Silvio 1.5 the buyer test rode it with the bars like that and liked it enough to request leaving the bars and brifters as they were. I'm most emphatically not evangelizing for that bar set up, just saying it works for me and at least one other person
Bob's bullhorn brifter set up looks good to me too, as does Ivan's. If I decide to add to my already extensive handlebar collection I may yet try one or both of those
