I would have more confidence in a jewel for your range of .5lb - 2.25 lbs over the TT special. I have no experience with the Diamond so it may be your ticket.. We have several Jewel triggers and have no problem with them.Im looking for a trigger that adjusts safely from 0.5lb - 2.25 lbs. This is kind of a wish range. I think I would like 4-8 oz when shooting off the bench and about 1.75-2.25lb in the field. The point of this post is that there is more to a trigger than weight.
