Things I liked:Good balance and very accurate with the open sights. I disliked the rear fiber-sight, because they are a little too small and one side of the fiber wire was not cut clean, making it take longer to aim because of the very dim sight. I haven't mounted the scope but it seems to be decent for a air rifle. Pyramyd Air was a pleasure to deal with. Even arranged local pickup at there office quick and easy. I see no reason to shop anywhere else. Things I would have changed:Rear sight setup is a single Fiber-Optic wire bent into both side of the wire is not cut clean it will produce a very dim sight, They did not leave any slack in the wire to repair. They really need to produce a specific manual for this gun. What others should know:If you clean your gun... use a soda straw inserted in the "Sliencer" to help guide the cleaning patch through the baffles and clean from the muzzle.
My Whisper liked the heavy pellets. I would suggest a trigger update and the Gas-Ram option to make this gun perfect.
