The primary complaint is that the stock prop is too slow. Sure, the stock prop is also down on thrust, but the lack of airspeed is the root-cause of the handling problems. The stock UM F4U is simply not fast enough to get the airframe more than just barely 'up on the wing'. In the case we were discussing (level inverted flight), it is the low airspeed that is causing the plane to fly so 'heavy on the sticks'. Bump the airspeed up by 5-10 MPH, and the problem disappears. Adding more nose-weight than what is required simply increases the stall-speed & increases the amount of elevator trim needed for level flight - which increases the induced drag. This exacerbates the problem.
