I do, because both I and several very close neighbors are serious CW 
contesters. The steep skirts of the 8-pole filters cascade with the IF 
to keep us from bothering each other when we get close in frequency. 
K6XX and I can work within 500 Hz of each other and hear the other as a 
strong signal.
