The fundamental reason for FTx needing it's own contest format is that 
it's a fixed rate which is set by software.  The exchanges are 
essentially synchronous and slaved to a common clock.  So if ops can 
keep the pipeline full, there is no differentiator among "run" speeds.  
All of the current RTTY contests have rate as a fundamental factor so 
using that format in a FTx contest makes no sense.  Additionally, as the 
rate is machine limited for the most part, if the FTx contest is going 
to have staying power it's got to offer some other challenge which op 
skill development can address.  High rates in RTTY depend on operator 
execution among a sea of variables - in FTx that element is essentially 
gone.

A format that rewards for distance seems a better fit - perhaps the Stew 
Perry format where points scale with distance and the exchange is grid 
square.  A contest built around something like that where the score is 
most influenced first by distance and then other factors a weak second 
would match well with the strength of these modes.
