I used to have one, but took it off because my thick gloves wouldn't fit through it. I never put it back on. I've found that bringing the fingers around the front of the riser and gently touching the front of the riser with my fingertips (index and middle fingers with my hand position, might be different for you depending on wrist angle) doesn't affect my shooting at all and the bow can't fall out of your hands when shot. I hate to see people shooting with a wide open hand. This causes tension in the hand, where a partially closed hand is relaxed. With todays bows that hardly move when shot, you will probably see less and less of the wrist slings.
