For a medium-light pull of 1-2 pounds the Jewell is great, and I would probably choose it over a tuned 700, Timney or Shilen. For a 2-3 pound pull any will do fine.
Under a pound and I like the Jard a lot. Have them on a Remington 700 Classic .221 Fireball and a benchrest 6mm PPC. Very fine triggers.
