Personally I prefer to not use a sling, but certain times it is a must for days combing for lopers, mulies or elk. I use a neoprene sling and find it is quite comfortable. However a number of guys I hunt with are now using a " Boonie" Sling or some are called a safari sling. This sling allows you to carry the gun across the lateral of the body and when you shoulder it pulls away to not restrict movement. I tried one on our elk hunt, it was very comfortable and I liked the concept a lot, so much so I am thinking hard about adding one to my gear bag.
