Do not forget the alpha-Monocerotids, where the parent comet is unknown
but the period is certainly long. And the 1935 Aurigids with parent
Comet Kiess of the period of the order of 2000 years. However, these
comets do not produce meteor outburst just behind the comet. See
the discussion in Jenniskens and van Leeuwen (1997, PSS 45,1649).
The catalog of Cook (1973) shows two meteor showers (not outburst)
associated with nearly parabolic comets: omicron Draconids and
Comet Metcalf and Leo Minorids and Comet Zanotti.
In any case, the Linearids may be worth to look for.
