I found the Vero Vellini the most comfortable, stay where ya put it sling I have used to date. Had it on my Whelen (10=lbs) and it was nice to carry. Put one on my 444SS as well. It is nice and wide at the shoulder spot so ite distributes the weight well. The reinforced neoprene also takes away most of the bouncing shock felt in the "solid" designs. Take it from Mikey......."TRY IT, YOULL LIKE IT"
