I ordered a lighter spring for my 870 but I didn't feel like it reduced the pull weight by much and most of all, it didn't take out the creep. I recently put the timney sear and lighter spring in my 870 and it made a big difference. The timney did not take out all of the creep but it is a lot better. I try and justify spending the money because I can use the medium weight spring in another 870 of mine. All in all, I would buy the timney again.
