Did you guy's notice a big diff. in noise between the two? I'm also considering a new one and from what I've read so far they are both going to draw a whole lot smoother than my 02 MM, noise is a pretty big issue for me, I'm going to try and shoot them myself this week but the only dealer around only has a Pat DC,I wonder how mucher louder that is than the singles, I guess I'll have to do some driving to find the Pat SC and Liberty to try, but my wife tells me I'm deaf as a stump and we all know deer are not ,so your impressions would sure help.
