The 527 trigger is wonderful. The regular trigger can be adjusted to slightly below two pounds. There is a lot of side-to-side play, though. If you don't pull straight back, it can feel like creep.
Even though the set trigger is so beautifully light, the fact that you push it forward creates a very looooong overtravel. Some people might not like that. From a rest, it really doesn't matter.
Oh, and jeclif, I think you can make the set trigger at least a little bit heavier if you adjust the set screw that is visible from inside the trigger guard directly in front of the trigger blade.
