Drop bars vs. alternatives tends to be a personal choice that lots of folks have strong opinions on.
I prefer more upright riding positions, much closer to fully vertical than an aerodynamic tuck. Also, I like to be able to stretch my back and neck by rolling forward and back while riding.
There is a real issue with a variety of riding positions, no matter what kind of bars you ride on.
When I looked at the photo you posted I did have some concerns about that. My solution to a varied riding positions is bar-ends mounted at a fairly steep angle. I can mix up left and right hands up and down them, cup my palms on top of them to get fully upright, and pull back against them on ascents to get more leverage.
I wasn't sure how well bar-ends would fit onto the Jeff Jones bars.
FYI, here are some photos of my setup
