Well boys and girls. The Guardian arrived today. After carefully looking over the design, I set it up to shoot. What were the results.... They have a winner on their hands here. This is one of the quietest, shock free bows I have ever shot. That is not the best part, this thing aims and balances nearly perfect. I would say it aims like a much larger bow. The pin was very steady while I was shooting it. I need to spend a bit more time testing. I got about 50 shots thru it today. I already am considering a Smoke Chrome model for 3D. Sorry if I sound like a fanboy but this is a great shooter. Oh and yes, I put it in the Xpress to install a peep with no problems.
