Not really, I only investigated shorty bars. I just know there are differences. I think Rogue and Elitefts and other places have explanations. That one site I linked to a while back about rubber matting also has a section on bars: http://www.garage-gyms.com/vulcan-elite-3-0-olympic-weightlifting-training-bar-review/ Yah, they'd be a good bet for advice. Maybe buy one bar at first, since how you like it, which lift it feels best on, and go from there? Happy hunting!
