I shot a 71 lb. Guardian about a month ago - very impressed - didn't feel like it could possibly be over 64 or 65 lbs. Shot a 60 lb. Guardian yesterday. It felt like a 55 lb. bow. The owner and I shoot the same arrow; and he is getting2 fps more speed than I am with a 1" shorter draw length and a 1" shorter arrow. Hand shock is about as low as it gets with these bows.
