In a way, when you pull through the first stage of a Jewel, the second stage becomes the actual trigger. I just recently increased the first stage pull up from about 2 lbs to about 3 lbs, and the second stage to one pound. Now when I pull through the first stage, I have to be very careful to stop at the 2nd stage without pulling through it inadvertently and firing the gun before I'm ready. But, there is no mistsake about pulling through that first 3lb stage of the trigger, and so it is very safe in that manner compared to a straight 1lb trigger. ie; what I mean by that is that I'm already on target when I've pulled through the first 3lbs of the trigger, but I have to concentrate and be careful before I tighten up on that second stage which breaks very easy after pulling through a heavier first stage pull. (No I'm not 3 feet off target when that happens.....it just usually becomes a flyer that is .25" to .75 off of the group)
But if you insist on a straight 1 lb light trigger and you want the best, then go with the Gieselle. Expect to pay.......no free lunches with that trigger.
EDIT: Oops, my bad.... I reread the thread and saw that it is Chisolm who wants a 1lb trigger. Not sure exactly what pull weight that you're looking for.
