 From the designers who brought us the "ten-year key clicks"?  Let me 
guess now...


Another point about AFSK is that, to achieve its full potential, the 
drive level needs to be adjusted quite carefully when hopping from band 
to band.  That isn't a promising scenario for the later hours of a 
contest, which is why in principle I prefer FSK - it may not be the very 
best on some rigs, but it won't be truly awful like badly adjusted AFSK, 
and it *will* be consistent.
