ps, trekking bars are inexpensive, like 25 bucks, and I tried some on my Troll for a while, and I see their big advantage is the width. For riding on gravel etc they would have a good wide hand stance, and of course the diff hand positions.
I double taped them , all around, and my wife likes them for the varying hand positions.
I guess to be fair, the only thing is that when your hands are on the widest postion, you have to bring your hands back in to shift and brake., and the inner part isnt as wide as a riser mtb bar, or Jones bars and all that sort of bars.
I do have an old commuter bike I put my butterflys on after deciding to go to drops for my troll, so I ride them regularly, and I find I usually have my hands on the outer widest part, my hand in the same shape/position as when on the hoods of a dropbar bike, which I find the most comfortable, but like how I can go to the inner area or far forward.

the good thing with trying either trekking or jones bars and similar, is that if you have trigger shifters, you can use them on all of these bar types, and probably even not have to change cables and housing to do a bar tryout change.
I havent ridden on Jones bars enough to know how they are with long riding time and day after day riding.
I still have the pair that came on my wifes bike, and one day will change my troll to them just for fun.

Oh, as you know, the 2017 and up Troll frameset can take even wider tires, up to 3in both front and back now, so a real plus for comfort and helping with bike handling with looser surfaces.
Again, its a cool bike.
