Eric, changing props to try to avoid the plane hooking left is a total waste of time and money in my opinion. Use the prop that is best suited for your engine. If your radio has exponential then add a little negative expo to the throttle and rudder channels. When taking off, add just a little throttle and allow the plane to start rolling good before adding a little more throttle all the while steering the plane with the rudder. If you find it very hard to master that technique then install a Futaba GY401 gyro on the rudder channel and use it in the heading hold mode for takeoff only then change to the rate mode.

There is a good thread here about using a rudder gyro on an airplane.
