it all depends on what you'd feel comfortable on, the nightstar is a sportster so its going to be small and someone your size will probably feel too big for it, someone your size would probably feel more comfortable on the street bob, but you have to find the bike more comfortable for you so sit on a few and maybe even ride 2 or 3 around the harley shop parking lot if they let you, you can also get aftermarket handlebars, seat and foot controls if you want to feel more comfortable
