we often get asked the question; to concave or not to concave? No matter how hard we've tried, we haven't been able to obtain hard data to which is better. It boils down to a matter of preference.
      It seems most would agree that a concave hanger is shaped more closely to the human shoulder. Therefore, many would agree concave hangers are more appealing since they fill the shoulders "better".
      If your most of your racks are T-stands are forward facing, the concave hanger may show slightly better.
      If most racks are circular then you may not get the advantage. Some would argue that concave hangers take up more space.
      We've tested this theory and it holds some truth although the difference is truly negligible. The concaves fit together ("spooning effect") thereby, reducing most space issues. The straight hanger is tried and true. It shows well no matter what the circumstances. The shoulders fill out just fine.
      Ok. So to make a long story short...It's a matter of preference.
