[Elecraft] 5 pole vs. 8 pole filters

[aa4nc at aol.com]

After operating a few contests with my K3, I think I may need to upgrade roofing filters, especially on SSB. I have the stock 2.7 and the 5 pole 500Hz CW installed now. 

Can anyone comment on the real world contest performance of the 8 pole vs. the 5 pole filters? On SSB with the width dialed in to 1.8-2.0 Khz, I have stations at S9 and above that are easily copyable at over 4 Khz wide which makes it tough on a crowded phone band. 

I'm told that the Inrad supplies the filters to Elecraft, so is there really only one filter source? 

Thanks,

Will
