DAX AFSK vs FSK RTTY for RTTY

It appears to me that the spectrum of AFSK RTTY signals is so good with DAX that there is little to be gained implimenting FSK. 1) It would be hard to make the FSK spectrum any cleaner than AFSK via DAX 2) FSK using RTS/DTR for FSK signalling can have serious element timing issues due to PC timing uncertainty. 3) These days, very few serial com ports can be configured for 5 bit / 45.45 baud on TXD Just a thought.
