Nick,

Best layout is similar,  Bus down one site to the NO contacts
and the wiper is the end of the filter and when in the off poistion the
wiper sits on the NC contacts to ground shorting the filter.  So a filter pick 
enables the relay and filter and no pick the filter is shorted.  Reduces
the effects of stray capacitance.

That and copper pour under everything and opposing side. lots of vias to 
tie them together especially along signal tracks.
