Does anyone have a bias against aluminum handlebars on a touring bike?

I'm looking to replace the drop bars on my 54cm Surly with something the same size and shape but with a flat top on the bar. My hands find this much more comfortable. Is there a term for the flat areas on the top of drop handelbars?


I was considering something like the ControlTech Formidable CL Handlebar but would like something wider.

thanks.
