I don't know why you need feedback. If these are what work for you, your body will give you the only feedback needed, just as it gave you the feedback you needed to know to stop using the drop-bars you previously equipped.
I might experiment with a butterfly-bar .... having done some longer rides/short tours with a flat-bar bike, I can see where different hand positions might be good for the whole body, if you ride for hours at a stretch ... but the myth that you cannot tour on flat bars is disproven by the hundreds of people I have seen post photos online of their flat-bar touring rigs ... many of these folks have covered whole continents on flat-bar bikes, bike-packing, with panniers, or with trailers, or some combination.
If your bike is well-fitted to your body, flat bars are fine for distance. If you find you want bar-ends or something ... then you will do that.
Also, I see no reason why you couldn't attach aero clip-ons to flat bars. Some tourers use clip-ons not to get under the wind (or not entirely) but to be able to rest on their elbows, to relax the rest of their bodies a little.
One a tour I passed a guy coming through (I think) the Colorado/Kansas transition zone, where the winds were insane. We were going in opposite directions so I couldn't ask him about it, but he looked so comfortable, laying down on his armrests and spinning away up the endless rolling hills in the high winds ....
