Ted Thorn and I each made our own versions of a sling keeper unbeknownst to each other. There were a couple threads on these at the backpack hunting forum last winter. Basically, I'd tried the Dark Mountain "Slingsaver", and found it essentially worthless as its wrap-around strap rubbed into my shoulder making it raw... I chucked it in the trash and built my own.
Here's the link for more:

A small piece of Gorilla duct tape eliminates the velcro issue on the Slingsaver if you have a chafing problem like Brad. The four guys I hunt with all use Slingsavers for rifles and a crossbow without issue.
Since I started using one of the rubber slings (Slogan Outdoors) I haven't needed any type of sling retainer.
