I have tryed a wrist loop in the past, but didn't like it very much. I use a toggle on all my slings and it works well for me. The toggle is made from a birch dowel and is long enough to cross over two fingers(at least, could be more). The retension line is either tied on to the toggle with a clove hitch, or if the toggle is nice and fat like 3/8" it can be drilled the retension line passed through it and knotted with an overhand knot. The grip is, the toggle over the first joint of the middle and ring fingers, the retension line exiting between these two fingers, the hand held in a semi fist with only the fingers currled. This is an easy hold not a death grip. The toggle is easy on the fingers; with it you can hurl some big rocks and no real pain.

Ask me about slinging for fun and profit.

WalkingBird, tell me about slinging for fun and profit.  lol.

I forgot to mention that my usual grip is the pinch grip holding both cords between my thumb and forefinger. so I can just release everything as one, and retain the payload in the pouch better until the intended time of release.  I use the smallest retention knot possible to prevent the projectile or cord snagging it.

With practice, I was surprised how fast and hard I could spin the sling, and still maintain complete control over the payload even with a very thin cord, and tiny knot, so long as I was not wearing gloves.  about 4-5 0z is my ideal wieght for a stone or glande/egg sinker, and I don't find that heavier stones that put undue strain on the grip are usually worth the extra sacrifice of safety, control and the sensitivity (which is very possibly the most critical factor in achieving accuracy, power and consistency), to say nothing of velocity, in return for a little extra weight and "smash" factor.

I admit that there are special cases where this doesn't apply (such as with multiple projectiles, etc.), but generally my stones do much more damage to the intended target when they are accurately shot out (with adequate weight, good shape for the intended purpose and a composition consisting of good hardness and toughness) at higher speed, than heavier, slower ones do.  I find that for me, at least, the pinch grip allows me to spin the sling faster without losing the retenion knot and stone to overwhelming centrifugal (outward) pressure.  I can therefore sling a lot farther and harder with it.
