You are going to get a variety of opinions on this one. I have owned an LDA for the last year and I really like it. A smooth and consistent 5.25 lbs trigger pull is great, because of the take up it does not feel that heavy. I mainly shoot in the open division and I was initially worried about going from a light 24 ounce trigger to the LDA. There was no issue.
Give one a try, I think you will be surprised on how good they feel.
