I'm trying to make my mountain bike more comfortable by giving myself a more upright riding position.



I'm debating between these two shapes:




Even though I own a mountain bike, I ride on flat terrain and rarely shift gears. Do you think I would experience discomfort in my shoulders from the hi-riser bars? Would turning be more difficult in the handlebar where my hands are lower to the ground? Please share your experiences with these type of handlebars. Thanks a lot.
