For the average shooter I don't think it's going to be a real big deal to be honest.
If you were a heavy competitor in 3 gun, or doing timed shooting, then maybe you want a light-weight trigger. But on an AR that you might be carrying from location to location, there isn't really a plus side to have an airweight trigger.
I am not familiar with this companies' product though, could you post a couple of pictures for the pure gun pr0n addict in all of us?
