It sounds to me like your plane may be too nose heavy. I know this goes against conventional wisdom, but believe it or not nose heavy aircraft are much more "snappy" than properly balanced aircraft. If you have alot of throw and the plane is not very pitch sensitive, try moving the CG back a bit, and reduce the elevator throw. I usually set a plane up with the CG towards the rear of the manufacturer's recommended range, then shift things around after flying it some to suit my tastes. When I get finished, sometimes I'm way behind the recommended range. Most manufacturers are very conservative with the CG locations. Next time you go out to fly move your battery or reciever back or add lead to the tail, and see if that helps. In my opinion, nose heavy airplanes are much harder to fly than slightly tail heavy planes.
