how do most o' ya'll like your frames? with a standard kinda tight clearance or a little extra room? i can't decide between a 54 or a 53 frame. the 54 is tight and i dont wanna sing soprano but will i sit too upright on a 53 or it futzing with bar height an option?

and also what does stem size have to do with anything? i'm on the verge of ordering an iro and he has options as to stem size. like what is the difference between sizes? my options are 80 to 120. what up? sorry if these are stoopid ?s.

thanks!
