7/8 ballad with 70-200mm and Canon 5D II is not lightship. The red neck and irritated while it's not terrible. Transpired to 40 ° on the manufacturer's strap not good. Strap change for a more flexible that not tear the skin. Resulting in more vivid to neck. Flexible strap which bounces the bottom case and does not give blows to the neck when walking. Tried it was adopted. Bought two different strap and I still prefer the Kaavie neoprene Quick release to OP / Tech Pro Strap which is a little less flexible and harder on the neck.
