How about using pfChanTravMode(...)

        pfChanTravMode (chan2, PFTRAV_DRAW, PFDRAW_OFF);
        pfChanTravMode (chan1, PFTRAV_DRAW, PFDRAW_ON); // switch on chan1

>From the man pages:

     For drawing, mode is either PFDRAW_OFF or PFDRAW_ON. PFDRAW_OFF
     essentially turns off chan. No culling or drawing traversal will take
     place. Drawing is enabled by default. pfGetChanTravMode returns the
     mode corresponding to trav or -1 if trav is an illegal or unknown
     traversal type.

Hope that helps,

K.
