Quoted:
I have a 4lb velocity trigger in one rifle. It's pretty good, but I think if you had a reduced power hammer spring and a good quality "normal" FCg, you'd be hard pressedto tell the ddifference. I got this trigger to replace the worst trigger ive ever had in a lpk, and it was a huge improvement over that, but compared to one of my nicest feeling "stock" triggers, it wasn't $100 better.  Maybe you'd notice a bigger difference with a 3 lb version, but it felt scary light to me, so I got the heavier one.  I'm also not really hot on using set screws to pinch the trigger pins in and more set screws on top of the first set to jam them in.  I haven't used it much yet, but I'll be surprised if I don't end up having the trigger pack come loose at some point.  I didn't put any locktite on the set screws when I installed it, which I should have, but we'll see what happens.
