I discussed this recently with Will Beemer. He suggested having tapered pins that start at 3/8" and go up to 1" body, over a very long taper.
This way one size fits all.
You can use them for 3/4" holes up to 1" peg holes.
And he also suggested that they be made in sets of six.
He personally owns at least 24.
Loops are good as you can put another pin in the loop to use to pull it out, if stuck. And also to turn the pin to help free it up.
