For those who have put in and tested many of these, are you finding there are situations in which you go back to an -ND, -CL or other RRD dimmer control for some reason (setting aside "well i still had some in my inventory" reasons), or is -PRO really now the ultimate lighting dimmer for the RadioRa line and works the best in pretty much every situation? Second - if the RRD-PRO really is now the ultimate control, shouldn't we expect a revised Hybrid Keypad that is based on this new circuitry as well? If I remember right, they previously modified the Hybrid Keypads when they came out with the -CL dimmers? Thanks all!
