@257Roberts,
Re sling pain, have you thought of getting the sling lower on your hand? The back of the hand, by the knuckles, has lots of small bones to be squashed. This may just be a Smallbore thing, but I see more good shooters who place the sling lower, over the base of the hand/wrist, avoiding the wrist knuckle though, that hurts! Having broken my scaphoid some years ago I find a glove with stiff-ish coating all the way to the cuff cushions the sling acceptably.
Keeping the wrist straight seems good to me, although some very good shooters don't. Having the handstop slightly to the left of the bore helps, if you want the stop in the thumb V and the rifle bearing on the base of the hand rather than the thumb or palm.
Thune slings are excellent. Hata slings are often recommended by US shooters; the material is similar to Thune's Biothane, but the cost is lower. Avoid having the sling pull from the inside, the brachial artery and nerve plexus will thank you. Personally I like the sling to pull straight, not from the outside, against the meat at the back of my arm. I have tweaked the cuff so it's symmetrical, and bolted it to the sling keeper.
