I am not going to make up your Mind for you .. though I wouldn't want to re elect your Mayor, If you want my Opinion.
My bike shop in my small town has a Variety of different Handlebars to hold in your hands and hold over your Bike .
You are in a Large city the selection should be even better.. take the bike go in and try a few in person.
stem is 1 inch , so bar center is same and the rest of the handlebar tubing is 7/8" standard uprirght bar , notthin oversize.
