The top RTTY contesters have learned that -- they have abandoned dual peak filters and now use 500 Hz bandwidth, narrowing only in the presence of very strong signals in the passband.
The bandwidth alone is not the whole story. Although I'm not a top RTTY contester, I have developed and used a constant delay discriminator over many years. You can find details here: http://dj0ot.darc.de/discri.pdf. The picture on the tuning scope display is here: http://dj0ot.darc.de.
