If so, you can check if your receivers are compatible with the 7PX. If so then you can save some money on receivers and keep the 3PK as spare,
The 603FF and 603FS do not work with the 4PX or 7PX, I know because I was pretty disappointed when I upgraded. If you really like a drop wheel, you could go with a used 4PX. I had a 4PLS for a while and saw no issue with it, I just got a good deal on a 4PX.
