[Elecraft] K3 options input sought

[david beckwith]

I am upgrading the shack from a K2 to K3. I have a nice Palstar tuner and an ACOM amp.  I am mostly a SSB guy, not big on contests or FM.  Given these resources and needs my planned configuration for the new K3 is:
K3/100  KXV3A IF Out and RX Ant. General coverage RX bandpass  KDVR3-DVR  KUSB 500 Hz 5pole CW filter and 6kHz AM/ESSB 8 pole filter.  Thoughts? Am I unwise for not including the internal ATU even though I have the Palstar? Thanks and 73  Dave
