Yes, I can confirm K9CT uses BP filters on his 6700's. His main reason for
switching to mostly 6700's at his contest station was for the "simplicity"
of being able to operate SO2R or multi -2  without the need for all the
access cables and extras required with the K3 set up. The WiFi ability that
comes with the Maestro made networking wireless as well. I believe he still
uses a K3S or two at his home station and uses K3S's on DXpeditions. 

There are conditions and reasons where each platform can win, with proper
configurations, tools  and expectations.
